氰化提金中降低氰化物消耗的研究
Study on the Decrease of Cyanides Consumption in the Cyaniding Extraction of Gold
摘要
Abstract
In the cyaniding extraction of gold , in order to decline the cyanides consumption , increase the benefits and reduce the environmental pollution , many measures were used to the purification and regeneration of cyanide solution such as combination with the industrial production practice , by strengthening and improving the ventilation equipments , adding the right amount of lead salts, controlling the appropriate concentration of CaO , keeping pH around 12, at the same time , reducing the copper ion accumula-tion in the circulation solution and returning the barren solution to closed cycle .As a result, the cyanides consumption was greatly reduced, and the cost was declined , the economic benefits and environmental benefits were improved significantly .关键词
