METHOD OF RECOVERING FINE GOLD FROM HYPERGENE ORES Russian patent published in 1998 - IPC

Abstract RU 2114201 C1

FIELD: gold mining. SUBSTANCE: method, in particular, relates to quantitative evaluation of fine gold content in different-oxidation degree hypergene ores with loose matrix and can be used for choosing correct ore processing and enrichment flowsheet for selectively dissolve gold. For that, starting material is treated for 1 h at pH 3-6 by hydrochloric acid solution in presence of 0.1 M ferric oxide at solids to liquid ratio 1:(10-15). EFFECT: enhanced process efficiency. 1 tbl
