摘要
探讨在矿物的铜渣中氰化条件对金银浸出率影响的原因，提出其提高金银浸出率的最佳氰化条件，为工业提取金银生产实践提供依据。结果表明，浸铜渣中NaCN用量为10kg/t，液固比为2．5，运用炭浸法（CIL），氰化时间为16h时效果最佳。
The causes for the extracting rate of gold and silver from immersed copper sediment influenced by cyaniding conditions are chiefly investigated, and the best eyaniding conditions to increase the extracting rate of gold and silver are proposed as well, with the purpose of providing basis for industrial extraction of gold and silver. 3＇he result indicates that effect is the best when the dosage of NaCN is 10 kg/t from immersed copper sediment, contrast factor of liquid and solid is 2.5, making use of CIL, and the eyaniding time is 16 h.
