摘要

FIELD: metallurgy. ^ SUBSTANCE: inventions relate to gold extraction from solutions with low concentration at presence of ions of other metals, for instance cleaning solutions of gold-extracting plants, brines of potassium manufacturing, geothermal water, water of brine lakes and salt water. Essence consists in that through powder of metal-restorative it is passed gold-containing solution with low concentration at presence of ions of other metals during 2-240 hours. In the capacity of metal-restorative it is used lead-plated zinc powder of grade +0.001 mm - 2 mm with lead content 1-90 wt %. or powders of metals, used at temperature of solution not less than 50C and selected from the group: Zn, Fe, Ni, Pb, Sn, Sb, of grade +0.1 mm - 5 mm. Additionally before cementation powders are placed in cartridge. Received after cementation gold-containing concentrate is separated by means of intensive mechanical agitation, it is treated by nitric or acetic acid. Gold sediment is separated by filtration, dried and molten with fluxing additives with receiving of crude metal. ^ EFFECT: increase of effectiveness and selectivity of gold extraction from solutions with low concentration. ^ 3 cl, 1 dwg, 3 ex
