METHOD OF EXTRACTION OF NON-FERROUS, RARE-EARTH AND NOBBLE METALS FROM REBELLIOUS MINERAL RAW MATERIAL |
摘要 |
FIELD: hydrometallurgy of extraction of non-ferrous, rare-earth and noble metals from rebellious raw materials containing natural carbon or other rebellious compounds. ^ SUBSTANCE: proposed method includes treatment of rebellious carbon-containing mineral raw material by oxygen-containing oxidant followed by extraction of noble metal compounds from liquid phase. Treatment of carbon-containing mineral raw material by oxygen-containing oxidant is carried out in presence of reductants possessing donor-acceptor properties which are expressed in the fact that at first stage of chemical reactions, reductants give off their electrons to oxygen-containing oxidant, forming stronger oxidant as compared with first one in form of short-lived radicals and intermediate products of oxidation of donor-acceptor reductants which are also used as oxidants. ^ EFFECT: increased extraction of non-ferrous, rare-earth and noble metals; low cost of process. ^ 3 ex |
