PROCEDURE FOR EXTRACTION OF FERROUS, RARE, RADIOACTIVE AND PRECIOUS METALS FROM REFRACTORY MINERAL RAW STOCK |
摘要 |
FIELD: metallurgy. ^ SUBSTANCE: procedure consists in processing raw stock with solution of donor-acceptor oxidants and reducers. Pulp produced upon raw stock processing is dried to complete evaporation of water and is subjected to burning at presence of air or blasted with enriched oxygen. Pulp is burned at temperature sufficient for carbon burn-out, but without formation of non-soluble salts. Upon cooling material produced after burning is leached and there are produced process solutions containing extracted metals. ^ EFFECT: high degree of metal extraction at high efficiency of production. ^ 3 cl, 2 tbl, 3 ex |
