  Engineers at the Donskoy Ore Mining and Processing Plant of JSC TNC Kazchrome, in Kazakhstan, have successfully completed trials of a first-of-its-kind industrial flotation technology to increase the enrichment of chrome oxide-bearing tailings, Eurasian Resources Group reports.

  Kazchrome, the world’s largest high-carbon ferrochrome producer by chrome content with a total resource base of over 200 Mt of chrome ore, is owned by ERG.

  The novel technology is part of the group’s R&D efforts to maximise chromite concentrate output and reduce the site’s environmental footprint, the company reports, with the process yielding the recovery of over 55% of chrome oxide and conforming to the applicable requirements for concentrate used in ferrochrome smelting.

  As a result of these trials, the flotation technology will be used to construct a new facility to process over 10 Mt of chrome oxide-bearing tailings with a planned annual capacity of 1.7 Mt for 450,000 t/y of chrome concentrate, ERG says.

  Benedikt Sobotka, CEO of Eurasian Resources Group, said: “This pioneering technology is a major milestone on our path towards ensuring sustainable and low-cost chromite concentrate supply for our operations in Kazakhstan, and is part of the group’s broader strategy to reinforce our leading position in the global ferrochrome market.”

  Sergey Opanasenko, Chairman of the Management Board of ERG R&D Centre, added: “We are very pleased with the results of the flotation trials, particularly considering the complex mineralogy and physical characteristics of our ores. Building on this success, we look forward to working on incorporating this technology into the design of our new tailings processing facility.”
