METHOD FOR DEVELOPING OFFGRADE COMPLEX ORE DEPOSITS |
摘要 |
FIELD: mining. ^ SUBSTANCE: invention relates to the mining and can be used for developing the offgrade deposits of copper pyrite ores to receive the rich copper-bearing ore for following refinement by enrichment, hydro or pyrometallurgy. The method enables improvement of the quality of minerals directly in the Earth interior. The method consists in: a) research of the ore body deposit and assigning them to the donor and acceptor ore bodies; b) leaching copper from the donor ore bodies at their bedding by use of the sulfuric solution, until the copper concentration in solution is more than 0.2 g/dm3; c) refinement of the said copper solution off mechanical impurities and reducing pH of the refined solution to 2.5-3.5 U. Eh is more than 0.11V; d) enrichment of the acceptor ore bodies their bedding by use of the refined copper solution by precipitating copper at the acceptor body; e) the following extraction of the ore from the acceptor enriched bodies. ^ EFFECT: improvement of quality of minerals directly in the Earth interior. ^ 5 cl, 2 dwg |
