Rio Tinto's<br />
ilmenite project in<br />
Madagascar is one<br />
of the world's most<br />
honored resource<br />
projects of all time.<br />
It was at the time also the largest<br />
project ever undertaken in<br />
Madagascar, an island state that<br />
is home to 200,000 species of<br />
animals of which 150,000 exist<br />
nowhere else on the planet.<br />
<strong>Hatch</strong> was most proud of the fact<br />
that it could recruit and train 85<br />
percent of the workforce from<br />
Madagascar and amass 12.5<br />
million work-hours without a<br />
lost-time injury.<br />
The project established<br />
precedents for very careful and<br />
incremental development, and<br />
still began production<br />
on schedule.<br />
Rio Tinto's approach to the<br />
novel development was one<br />
of sensitivity to Madagascar's<br />
unique ecology, and a singleminded<br />
determination at Rio<br />
Tinto's director level to respect<br />
the company's commitment<br />
to sustainability.<br />
After several years of discussions<br />
with local communities and<br />
national regulators about<br />
how the ilmenite sands could<br />
best serve one of the most<br />
ecologically sensitive regions in<br />
the world, Rio Tinto drew up a<br />
plan to create a dredging mine,<br />
much like Rio Tinto & BHP<br />
Billiton’s successful facility at<br />
Richards Bay, South Africa.<br />
Using a conventional cutter/<br />
suction dredge, a floating<br />
concentrator in the dredging<br />
pond, a land-based minerals<br />
separation plant, and associated<br />
infrastructure (including a new<br />
port facility, a power generator,<br />
a 20-km-access road, and a water<br />
supply), Rio Tinto developed<br />
"a model for future projects<br />
in Africa and elsewhere in the<br />
developing world," said Rio<br />
Tinto's Chief Executive Officer<br />
Tom Albanese.<br />
Despite its remote location<br />
and the need to educate and<br />
mobilize the local workforce,<br />
the construction was completed<br />
in three years and the overall<br />
project in five years.<br />

Strict access rules and<br />
performance standards were<br />
imposed on all site personnel,<br />
contractors and suppliers to<br />
guarantee that safety protocols<br />
were obeyed to the letter.<br />
When the project was completed<br />
more than seven million hours<br />
were expended including a run<br />
of five million without a<br />
lost-time injury.<br />
The project’s scope included<br />
all surface and underground<br />
infrastructure, a ventilation shaft<br />
sunk to 1,685 metres, and a<br />
production shaft sunk to<br />
1,750 metres.<br />
The underground infrastructure<br />
includes 25 km of lateral mine<br />
development, and, to prove ore<br />
body geometry, mineral grades<br />
and tonnage some 125 km of<br />
diamond-drilling.<br />
Nickel Rim is now producing at<br />
1.2 million tonnes per annum;<br />
however hoisting infrastructure<br />
is designed to extract up to a<br />
maximum of 1.7 million tpa of<br />

An incredible journey<br />
The design, manufacture<br />
and global transportation<br />
of the world’s largest autoclaves<br />
Each 780-tonne autoclave<br />
took 18 days to be<br />
transported just over<br />
120 kilometres from<br />
the port at Samana,<br />
Dominican Republic,<br />
to the Pueblo Viejo<br />
operation.<br />
The Pueblo Viejo gold operation<br />
in the Dominican Republic is on<br />
track for its first gold pour in the<br />
first quarter of 2012. But getting<br />
to this point has not exactly<br />
been easy sailing. Because<br />
the ore is double refractory, in<br />
order to access it, the project<br />
had to commission the largest<br />
autoclaves ever built and<br />
transport them halfway across<br />
the world from Malaysia to the<br />
Caribbean.<br />
Accessing gold<br />
Pueblo Viejo, a joint venture<br />
between Barrick Gold<br />
Corporation and Goldcorp Inc.,<br />
boasts gold reserves of<br />
approximately 23.7 million<br />
ounces. Barrick owns 60 per<br />
cent and is the managing<br />
partner. The sulphidic refractory<br />
gold deposit is being constructed<br />
to a 24,000 tonne-per-day design<br />
capacity. In the first five years, it<br />
will produce an average of 1.042<br />
to 1.125 million ounces annually<br />
(100 per cent basis).<br />
<strong>Hatch</strong> Autoclave Technology<br />
Group has been on the project<br />
since 2006 with the engineering,<br />
procurement, construction<br />
management (EPCM) contract<br />
for the core part of the refractory<br />
process, namely, the autoclaving<br />
facility and supporting oxygen<br />
plant. “It’s a double refractory<br />
gold ore, associated with two<br />
mineralogical issues: sulphides,<br />
in the form of pyrite and minor<br />
base metals such as silver,<br />
copper and zinc, which prevent<br />
cyanidation from directly<br />
recovering the gold; and a<br />
natural carbon component to the<br />
ore, which causes issues with the<br />
recovery under a conventional<br />
system,” explains <strong>Hatch</strong> project<br />
manager Kevin S. Fraser. The<br />
incorporation of autoclaving<br />
in the processing of the ore<br />
addresses these challenges.<br />
In the autoclaves, all sulphides<br />
are oxidized, producing<br />
sulphuric acid as a by-product.<br />
The iron, copper and zinc<br />
dissolve into the solution; then<br />
the acid is washed out in a<br />
counter-current decantation<br />
(CCD) circuit leaving free<br />
microscopic gold to allow<br />
for leaching in cyanide. The<br />
<strong>Hatch</strong> Advantage July 2011 | 11
underflow slurry is pushed to<br />
a carbon-in-leach circuit. Also<br />
in the autoclaves, the carbon<br />
contained in the sedimentary<br />
materials is oxidized with the<br />
combination of oxygen and high<br />
temperatures.<br />
Within the autoclaves, oxygen<br />
is the primary reagent. During<br />
design of the autoclaves, <strong>Hatch</strong><br />
included a heat recovery circuit<br />
that, combined with the nature<br />
of the exothermic reactions<br />
that produce heat within the<br />
autoclaves, makes the heat<br />
autogenous by design. “Without<br />
the heat recovery system, we<br />
would need some external<br />
heat source,” Fraser adds.<br />
“This way, we keep the energy<br />
needs down.” The Pueblo<br />
Viejo autoclaves are the largest,<br />
by weight, refractory-lined<br />
autoclaves built to date globally,<br />
with an onhook weight of 780<br />
tonnes when shipped lead lined.<br />
The massive structures are each<br />
5.6 metres by 34.8 metres, and<br />
will nominally operate at 230<br />
degrees Celsius. There are four<br />
in total.<br />
The grand voyage<br />
<strong>Hatch</strong> designed the autoclaves<br />
and provided quality assurance<br />
during fabrication. They were<br />
built by KNM Process Systems<br />
Sdn Bhd in Gebeng, Malaysia.<br />
“We had two full-time quality<br />
assurance inspectors on site<br />
throughout the 33-month<br />
fabrication,” Fraser recalls.<br />
The autoclaves were then<br />
shipped approximately<br />
10 kilometres to the Kuantan<br />
Port using a 24-line, selfpropelled<br />
modular transporter<br />
(SPMT) heavy-haul unit. At the<br />
port, they were loaded on the<br />
Beluga Bremen, a P2-class ship<br />
owned by Beluga Charters out of<br />
Germany, for its maiden voyage.<br />
The autoclaves were transported<br />
in two shipments of two<br />
autoclaves each on the Bremen,<br />
which used both of its 750-tonne<br />
cranes and needed six hours<br />
to load the autoclaves from the<br />
SPMT into the cargo hold.<br />
“We had two full-time<br />
quality assurance<br />
inspectors on site<br />
throughout the<br />
33-month fabrication”<br />
The ocean voyage took four<br />
weeks one way, heading<br />
through the Panama Canal to<br />
reach Samana in northeastern<br />
Dominican Republic. “Samana<br />
is basically an old and unused<br />
former cruise ship pier that<br />
was refurbished for the Pueblo<br />
Viejo project, including the<br />
autoclaves,” Fraser explains.<br />
There, the autoclaves were<br />
transferred from the Bremen<br />
onto a 4.9-metre-wide 22-line<br />
Goldhofer heavy-haul trailer unit<br />
to transport the autoclaves over<br />
120 kilometres to the Pueblo<br />
Viejo site, a trek that took about<br />
18 days, and had to be repeated<br />
for each of the four autoclaves.<br />
“I think I’ve walked every<br />
kilometre of that route – I’ve<br />
definitely driven it many times,”<br />
says Fraser. “The Goldhofer<br />
moves at an average of two<br />
kilometres per hour and can only<br />
operate during the daytime.”<br />
Prior to the autoclaves arriving<br />
in the Dominican Republic, the<br />
project of readying the route to<br />
get them to site took about<br />
16 months. Due to the sheer<br />
size of the autoclaves, there<br />
were a lot of interference issues<br />
to deal with: trees, power lines,<br />
communications lines, signs in<br />
villages that had been modified<br />
so they could rotate, and bridges<br />
(some had been temporarily<br />
reinforced to support the excess<br />
weight of the load; others had<br />
metal ramp structures added<br />
along each side to allow the<br />
Goldhofer to drive over them).<br />
The actual trek across the land<br />
with the autoclaves required<br />
a number of teams. Heavy<br />
lifting and transport specialist<br />
Mammoet Caribbean Inc. was<br />
responsible for driving the<br />
Goldhofer. A crane and ramp<br />
team moved the ramps – the<br />
team would go ahead, ramp<br />
up a bridge, and then once the<br />
Goldhofer crossed, dismantle<br />
the ramp, move ahead of the<br />
Goldhofer and ramp up the next<br />
bridge. A safety team acted as<br />
an escort and ensured all were<br />
well-fed and hydrated, while<br />
also providing necessary crowd<br />
control near towns.<br />
Upon reaching the massive<br />
gates at Pueblo Viejo, which<br />
12
is situated on a mountain, the<br />
autoclaves were transferred<br />
from the Goldhofer to an SPMT<br />
trailer unit, as it can rotate<br />
and manoeuvre tightly, using<br />
hydraulics for better accuracy.<br />
The autoclaves were transported<br />
to the north bench area of the<br />
project and negotiated into the<br />
autoclave building, where a<br />
jack-and-slide process was used<br />
to lift the large items to be slid<br />
sideways onto piers and lowered<br />
down onto two six-metre bearing<br />
plates and sixteen 70-millimetrediameter<br />
anchor bolts. “The fit<br />
was perfect,” Fraser says.<br />
By August, the first two<br />
autoclaves were on site, and the<br />
remaining two were there by<br />
mid-November.<br />
Brick by brick<br />
The autoclaves are constructed<br />
of carbon steel, with the vessel<br />
shell made of 100-millimetrethick<br />
plate. A lead lining was put<br />
in during fabrication to protect<br />
the vessel shell from corrosion.<br />
A team of 12 lead burners from<br />
JL Goslar GmbH & Co. KG<br />
welded approximately 60 tonnes<br />
of lead into each autoclave.<br />
Currently, at site, a refractory<br />
brick lining is being put in the<br />
autoclaves by Koch Knight LLC<br />
to thermally insulate the process<br />
and protect the vessel from the<br />
challenging conditions. The<br />
lining will be 300 millimetres<br />
thick, comprising four layers of<br />
brick. A team of 12 masons is<br />
working on site laying 98,000<br />
bricks in each autoclave.<br />
“Bricking the autoclaves takes<br />
talent – there are many nozzles,<br />
openings for pipes, agitators,<br />
internal structural components<br />
and so on,” Fraser says, “all<br />
with specific designs to ensure<br />
they are protected thermally<br />
and chemically and perfectly<br />
fit. The brick work started at the<br />
beginning of September 2010<br />
and will finish at the end of<br />
June 2011.”<br />

Every objective was met with the<br />
highly successful third expansion<br />
of Rio Tinto's UGS to 375,000<br />
tons per year.<br />
The project was fast-tracked from<br />
the outset and was completed<br />
three months ahead of schedule<br />
and $15 million under budget.<br />
During the 525,000 work-hours<br />
dedicated to the expansion<br />
project in a facility operating<br />
at full capacity there was not a<br />
single lost-time injury.<br />
Rio Tinto had concluded<br />
that a 15-percent increase<br />
of production could best be<br />
accomplished with two new<br />
production lines.<br />
15 % production increase<br />

The project won the<br />
Project Management<br />
Institute Project of<br />
the Year Award in<br />
Québec. UGS is<br />
at Sorel-Tracy,<br />
Québec, on the<br />
St. Lawrence River.<br />
The project was then entered<br />
into the International Project of<br />
the Year competition, against<br />
competitors from more than 60<br />
nations, and Rio Tinto captured<br />
that honor as well.<br />
It was a global project:<br />
• All the main production<br />
equipment was designed at<br />
<strong>Hatch</strong> Mississauga in Canada;<br />
• The preliminary design studies<br />
were completed in <strong>Hatch</strong><br />
Montréal and <strong>Hatch</strong> Sorel-<br />
Tracy; and<br />
• The structural engineering<br />
and steel detailing of the<br />
Slag-Preparation Plant were<br />
assigned to the team at<br />
Woodmead, South Africa.<br />
<strong>Hatch</strong>'s scope of services were<br />
engineering, procurement and<br />
construction management, i.e.<br />
the “full EPCM.”<br />
<strong>Hatch</strong> also designed the process<br />
equipment including the<br />
reactor, dryer, and classifier; and<br />
programmed the controls.<br />
More than 400 piping,<br />
mechanical, and electrical tie-ins<br />
were needed.<br />
A dozen major pieces of<br />
equipment were installed.<br />
Through it all, production<br />
continued without interruption.<br />
The Acid-Leach Plant was on<br />
stream after two days. The<br />
Slag-Preparation Plant was<br />
operational in a week.<br />

Impala<br />
Platinum,<br />
a milestone<br />
project<br />
<strong>Hatch</strong> developed an efficient<br />
electric furnace for Impala<br />
Platinum. Power needs were<br />
slashed by 25 percent, and<br />
electrode consumption was<br />
reduced by 35 percent.<br />
Impala Platinum had a clear<br />
objective when it asked <strong>Hatch</strong><br />
to expand its smelter and that<br />
was to increase production<br />
while cutting costs per unit of<br />
production.<br />
<strong>Hatch</strong> designed a single smelting<br />
furnace designed to operate at<br />
40MW, equal to the combined<br />
power of Impala’s<br />
previous four furnaces.<br />
The single furnace<br />
throughput is now more<br />
than the total of the other<br />
four furnaces.<br />
When the new furnace<br />
was commissioned, it<br />
achieved “astonishing<br />
performance indices,” says<br />
Bert Wasmund, Executive<br />
Director, <strong>Hatch</strong>.<br />
The new furnace uses<br />
25 percent less power per tonne<br />
of feed, and has 35 percent<br />
lower electrode consumption.<br />
Impala used <strong>Hatch</strong>’s proprietary<br />
refractory cooling and highvoltage<br />
technologies.<br />
<strong>Hatch</strong>’s specialized team of<br />
furnace technologists designed<br />
all components of the new<br />
furnace including the innovative<br />
35 % fewer electrodes<br />
25 % power savings<br />
three-dimensional (3D) structural<br />
binding arrangement as well<br />
as mechanical and electrical<br />
systems for the 40-tonne<br />
automated Soderberg electrodes<br />
that deliver power to the furnace.<br />
The Impala furnace No 5 in<br />
South Africa was designed in<br />
1991 by Nils Voermann, <strong>Hatch</strong>’s<br />
Global Managing Director,<br />
Technologies. He also led the<br />
team that commissioned the<br />

$1.26 billion project had a total<br />
of 5.5 million hours worked<br />
and more than 21,000 audits of<br />

Engineering design excellence<br />
produced:<br />
• Automated wagon vibrators<br />

health and safety hazards<br />
• Jetty widening on a single row<br />
of vertical piles to ensure the<br />
benefits of lower capital cost,<br />
smoother constructability and<br />
easier maintenance<br />
• Further expansion<br />
accommodated by the jetty<br />
widening and the vertical<br />

• Processes that allowed full<br />
production being achieved<br />
within days of startup<br />
• An enhanced working<br />
environment that is cleaner,<br />
provides good maintenance<br />
access and is less constrained<br />
for operational personnel.<br />
At program completion, a<br />
distinguishing operational feature<br />
of DBCT was the technology of<br />
two reclaimers simultaneously<br />
feeding each outloading<br />
conveyor/shiploader. This feature<br />
enables DBCT to efficiently<br />
blend cargoes out of the<br />
stockpiles which have enhanced<br />
terminal users' commercial<br />
positions in global markets.<br />
The DBCT 7X project scope of<br />
work included the introduction<br />
of 3D anti-collision technology<br />
that increased the advantage<br />
of cargo blending. In addition<br />
to the innovative higher bund<br />
walls in the stockyard, greater<br />
capacity, efficient blending and<br />
simultaneous machine operation,<br />
is only part of the engineering<br />

help cargo vessels ascend and<br />
descend the escarpment between<br />
Lake Erie and Lake Ontario in<br />
the Great Lakes system.<br />
Today more than<br />

FROM THE EDITOR'S DESK<br />
Improved safety programs<br />
lead to improved productivity<br />
Every dollar invested in<br />
workplace safety can deliver as<br />
much as $10 to a company's<br />
income statement, says a study<br />
funded by Liberty Mutual<br />
Insurance.<br />
A recent statistical study of<br />
construction records showed<br />
a strong association between<br />
improved safety and improved<br />
productivity.<br />
Another company's records<br />
agreed with that finding and<br />
went on to say that by cutting<br />
accidents in half, the company<br />
could immediately reap a<br />
12 percent improvement in<br />
productivity.<br />
Unknown is why a relationship<br />
between productivity and<br />
safety exists.<br />
The speculation is that<br />
companies that want<br />
both improved safety and<br />
productivity, simultaneously<br />
create cultures in which the<br />
employees see management<br />
supporting safety while at the<br />
same time demanding<br />
improved productivity.<br />
A meat processing company<br />
analyzed 10 years of safety and<br />
productivity records and found<br />
that the company could point to<br />
an internal rate of return of<br />
30 percent.<br />
It was clear too that large<br />
construction companies could<br />
claim better productivity and<br />
safety programs for the simple<br />
reason that they could afford<br />
to implement comprehensive<br />
safety training and supervision<br />
programs.<br />
Foster Wheeler examined the<br />
safety and productivity records<br />
of 19 major projects and 34<br />
million work-hours on site<br />
and concluded that the key<br />
performance indicators of cost,<br />
schedule, safety and productivity<br />
are all "interdependent."<br />
The School of Health Services<br />
at Purdue University concluded<br />
that the primary element that<br />
reduced falls from elevations<br />
on construction sites was the<br />
commitment of senior managers<br />
to promote safety as a priority.<br />
The second important element<br />
was training supervisors on how<br />
to promote safety. Leadership<br />
was found to be the key to<br />
success in improving safety<br />
results and productivity.<br />

Public Enterprises; and Coega<br />
which is that used by the Coega<br />
Development Corporation, the<br />

“Other spellings include<br />
Cougha, Coecha, Koecha<br />
and Koega. The name is of<br />
Khoekhoen origin for the<br />
river of the same name and<br />
means 'ground water.' Coega<br />
