RUSAL Lauches Pilot Plant to Produce Scandium from “Red Mud”
Nearly 2,5 t of primary scandium oxide concentrate can be produced in the new unit. In the course of 2014, a total of RUB 74 million have been invested in the project. For converting primary scandium concentrates into marketable commercial products, the company is planning to create a pilot plant, along with the technology needed. The content of scandium oxide is expected to reach 99,0 % in that case. The pilot plant will be capable of producing 500 kg/a and the market price for such products is between USD 3000 – 5000 per kg. Aluminium-scandium alloys would be produced at the RUSAL’s smelters from the obtained scandium oxides. Scandium is known to greatly improve the quality of aluminium alloys and having their own source for the raw materials would greatly reduce the costs for the company to produce these alloys.
