Baotou Rare Earth Concentrate 30% of direct smelting of rare earth alloy of silicon through the technical evaluation of new process plant Baotou Steel Rare Earth bear a \30, nearly 2,000 tons of rare earth concentrates, the production of more than 1,500 tons of rare earth alloy of silicon, very significant economic benefits. The project was February 27, 1997 passed the technical appraisal organized by the company CCS. appraisal committee composed of experts on the identification of technical papers were carefully reviewed and agreed that the project has a short process,ugg boots günstig, low energy consumption, product quality, etc., reached the advanced level of comprehensive utilization of Baotou Rare Earth Concentrate with low-grade and improve the production of rare earth ferrosilicon alloy structure of raw materials has opened up new avenues.
