FIELD: metallurgy.
SUBSTANCE: invention elates to device for cyanic leaching of gold from gold-bearing materials. Device contains tank for leaching with located gold-bearing material, collapsible tank, branch pipe for discharge and withdrawal of efficient solution and branch pipe for feeding of cyanide. It is outfitted by filled by alkali reaction vessel-closed scrubber, allowing siphon pipe, gas disperser HCN D pipe for feeding of alkaline solution and branch pipe for feeding of cyanide. Device is outfitted by pipe for gas distillation HCN and its feeding into reaction vessel - closed scrubber and pipe for feeding of air oxygen into tank. Additionally tank for leaching is implemented with internal perforated wall. Into space between external and internal walls of tank it is mounted siphon pipe connected to collapsible tank. In collapsible tank it is located system for solution blending branch pipe for discharge and withdrawal of efficient solution and gage tank for feeding of inorganic acid.
EFFECT: increasing of leaching speed of gold and improvement of environmental protection.
