Resumo
The results of studies of the hydrodifluoride leaching of the perovskite concentrate have been presented. It has been shown that processing the perovskite concentrate using fluoride technology enables one to transform niobium and tantalum into a solution, along with fluoroammonium salts of titanium, iron, and silicon, and to isolate rare-earth elements in the form of complex fluoroammonium salts mixed with CaF2 within a few stages.
