CBMM announced the development of a technology for the concentration of rare earths present in monazite, a mineral component of CBMM's ore. The development was achieved entirely in Araxá by the team of employees at the CBMM Technology Center and culminated in the production of two refined rare earth concentrates: double sulfate and hydroxide.
CBMM has made a significant stride to place Brazil among the few countries that possess this technology (rare earth extraction from monazite mineral). A major differential in the Company's accomplishment is that the rare earths are obtained as a by-product of the niobium manufacturing process, thus eliminating the need for additional mining.
CBMM invested approximately R$60 million to develop the new technology and will now focus efforts on a market study, and possibly the production of pure oxides. Potential customers have already expressed interest.
