STUDY ON THE PREPARATION OF ELECTROLYTIC MANGANESE RAW MATERIALS BY CALCINATION AND PURIFICATION OF LOW GRADE MANGANESE CARBONATE ORE
It analyzed the current domestic low grade manganese carbonate ore enrichment technology,and verified the chemical reaction process of the main process link of manganese carbonate ore calcination and purification through basic physicochemical analysis,conventional process characteristic analysis,and reduction sintering characteristic a-nalysis of manganese carbonate ore samples.By using high temperature calcination decomposition and reduction processes,a considerable level of comprehensive utilization of resources,intelligent control,and large scale equipment can be achieved.It has accumulated comprehensive experience in the process configuration and core equipment devel-opment for the design of mass production lines,and completed the technical reserve for the preparation of electrolytic manganese raw materials by calcining and purifying low grade manganese carbonate ore.
