氰化提金中，为减少氰化物消耗，提高效益，减少环境污染，结合生产实际，采用加强改进通风设备，适量添加铅盐，控制合适的CaO浓度，保持溶液pH值在12左右，对氰化溶液进行净化再生，同时减少循环溶液中的铜离子积累并使贫液返回闭路循环使用等。结果使氰化物消耗大幅降低，生产成本下降，显著提高了氰化提金中的经济效益和环境效益。%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 .
