摘要
针对云南某高碳低铜碳质银矿因含碳高,无法氰化浸出回收的问题。通过浮选试验研究,优选"两粗两扫三精"浮选原则流程,再辅以粗精矿再磨、碳质脉石抑制剂的使用等措施,取得浮选银回收率63.58%、铜回收率62.93%的试验结果,达到综合回收该类矿物铜、银资源的目的。
Aiming at the problem that a high-carbon low-copper carbonaceous silver mineral in Yunnan can not be recovered with cyanidation due to its high-carbon content, by conducting flotation test research, optimization of flotation principle process on ＂ two roughing, two scavenging and three cleaning＂, regrinding of primary concentrate, and using carbonaceous gangue depressant, the experimental results that the recoveries of silver and copper are 63.58% and 62.93% respectively have been obtained to recover comprehensively silver and copper in the mentioned ore.
