The Finnish corporate group Outokumpu is one of the
largest producers of high-quality stainless steel worldwide.
Its yearly melting capacity is around 2.5 million tons, and its
rolling capacity for warm and cold strip, long products and
quarto metal sheets is just under 2 million tons. The Finnish
plant in Tornio is the affiliated group’s largest factory, and
is unique in that it has the only fully integrated production
line.
The aforementioned production line starts in the EU’s
only chromium mine in Keminmaa, where approximately
200,000 tons of lump ore and 400,000 tons of fine
concentrate are produced every year. The steel plant has
two production lines: one with 100 tons and the other with
150 tons and converters in which the melted ferrochromium
is processed with steel scrap. The warm rolling factory
produces steel with widths ranging from 1 to 1.6 meters
and with a thickness of up to 12 mm. Most of the coils made
there are then turned into acid-resistant stainless steel
sheets and plates at the cold rolling factory for customers
all over Europe.
Due to the high separation density necessary, the alljig®jigging
machine is in many cases the only economical
solution for producing high-quality metal that can then
be directly reprocessed metallurgically. In addition, the
cleaned slag can also be sold as valuable aggregate for
concrete or road construction.
In the first half of the decade, there was a great demand
in Western Europe and Africa for allmineral’s innovative
processing technology, but currently the spotlight is on
countries in the CIS.
Initially, allmineral set up two lines, each with two alljig®jigging
machines, for ferrochromium slag processing at the

Russian metallurgical plant Cheliabinsk (one of the largest
in Europe). Their throughput rate is 20 resp. 40 tons per
hour and machine.
Now allmineral has received an order for two alljig®jigging
machines to be used for upgrading the raw materials
enrichment for ferrochrome-production, the chromite ore
itself. And following their first order for an alljig®-jigging
machine in 2007, another chromium ore processing plant,
owned by the Kazchrom company in Chromtau, Kazakhstan,
has just ordered another one.
Within a short amount of time, twelve alljig®-jigging
machines for slag processing have been put into operation:
two in Belgium, four in South Africa, four in Russia and two
in Finland. In addition, there are also the aforementioned
four alljig®-jigging machines for chromite ore benefication
for clients in Russia and Kazakhstan. In total, allmineral
has supplied over 400 alljig®-jigging machines around
the world, where they are used to efficiently sort not only
slag, but also coal, ore, gravel, sand, crushed stone and
recycling materials.
