New product developments Sabyasachi Mishra, Managing Director Introduction Allmineral Asia, a Kolkata based subsidiary of Allmineral GmbH, Germany came into existence in June 2009 and has made deep in-roads into the mineral beneficiation sector in India. It is equipped with world class technologies, both dry& wet, in beneficiation of coal, iron ore and other minerals to provide complete beneficiation solutions-concept to commissioning. In coal application, allmineral has unique dry jigging with no process water requirement. Additionally, with wet jigging & multi-stage heavy media separation system (Tri Flo ®), allmineral is the only company to provide such varied technologies to Indian coal industry. In iron ore too, allmineral has solutions for very low grade ores as well as from lumps to ultra fines. Allmineral Gmbh, one of the world leaders in mineral beneficiation, with its head quarter at Duisburg, Germany has subsidiaries in USA, South Africa, Poland and is represented in more than 20 countries through licensees & agents etc. Allmineral has worldwide successful installations, in countries like USA, Europe, Russia, Brazil, South Africa, Australia etc. Over the years, Allmineral has sold more than from allmineral Dr.Heribert Breuer, Chairman 400 nos. alljigs, 100 nos.

New Product Developments A Quantum Jump - gaustec´s new X-type Mega- WHIMS in operation with 700 tph :- It took Gaustec 5 years - from the first industrial unit to the biggest WHIMS ever built. And once again the Itaminas Mine in the heart of the Brazilian iron quadrangle in the state of Minas Gerais is the place to be. Where everything started in 2005 with a 120 tph gaustec 3200 the new Mega- WHIMS gaustec ® GX 3600 went into operation in July this year, at a capacity of 700 tph. Not by coincidence again the area of one of the largest iron ore deposits in the world became the birthplace of this new class of giant magnetic separators, where huge mining activities require huge equipment capacities. From the very first moment up to now gaustec is convincing the customers with simple but intelligent solutions, from operators for operators. The implementation of numerous improvements to the well known JONES- WHIMS concept were honored by the market. Easier maintenance, less energy consumption as well as more flexibility by means of more parameters to adjust, i.e. better performance, JANUARY-2011/32
led to more than 50 gaustec ® - WHIMS sold in five years only. And now with the new model capacities per unit have doubled at almost the same footprint, the same weight, the same energy consumption and the same efficiency, of course: The new gaustec ® - GX 3600 with capacities from 360 to 800 tph¹). At the Itaminas plant the new gaustec ® -GX 3600 is fed with hematite iron ore < 1 mm with a feed grade of about 54 % Fe and 23 % SiO 2 at a rate of 700 tph, 50 % solids. The product of this cobber stage is further upgraded in a second, already existing gaustec ® -G 3600 to a final product of plus 66 % Fe and less than 3.0 % SiO 2 . The tailings of the cobber stage are fed to a gaustec ® - GHP 150, which works as a scavenger, producing tailings with about 18 % Fe and 60 % SiO2. With the future introduction of a grinding circuit for better liberation it is expected that the iron in the tailings can be reduced to less than 10 % Fe, since by now only natural iron ore fines are processed. In addition to the general features of gaustec ® - WHIMS like l Independently adjustable magnetic fields of the rotors of up to 15.000 Gauss l Easy access to rotors for maintenance l Controlled feed distribution through improved feed box design l Optimized spray boxes for product washing of higher efficiency at less water consumption The gaustec ® -GX 3600 offers even more technical and economical advantages: l Lower specific CAPEX and OPEX per ton of feed l Less ancillary equipment required l Simplified processing flow sheet and plant layout That´s why the X in the new gaustec ® -WHIMS not only symbolizes the new pole arrangement but leads the way to increased benefits for the mineral industry by making use of the high capacity gaustec ® - GX technology. ¹) figures for iron ore, depending on feed characteristics, to be confirmed by test work Photo description “Gaustec - 3600 | Itaminas, Brazil| Tri Flo ® - the new generation multi-stage heavy media DMS Allmineral Asia Pvt Limited, has tied-up with the Italian company Ecomin S.r.l for providing new generation Tri-Flo technology-a multistage heavy media system for beneficiation of high ash Indian Coals.
