摘要
广西某多金属选厂浮选工艺流程中使用了氰化钠以改善硫锌分离效果,但该有氰工艺属于国家明令淘汰的落后工艺。试验采用巯基乙酸钠取代氰化钠并通过系列试验得到品位46.72%,回收率94.64%的锌精矿,该指标略优于氰化钠的工艺,并试验探讨了巯基乙酸钠抑制黄铁矿的机理,为选厂进行药剂改造实施无氰工艺提供了技术支持。
Sodium cyanide is applied to improve sulfur zinc separation of Guangxi muhimetallic process plant, but the cyanide process belongs to the backward process eliminated countries. Sodium thioglycolate is applied to instead of sodium cyanide in flotation separation, and zinc concentrate with grade of 46.72%, recovery rate of 94. 64% is obtained by a series of optimization test. The processing index is better than the cyanide process. This paper discusses the mechanism of sodium thioglycollate inhibits pyrite. It can provide the technical support for the the non cyanide agent transformation of processing plant.
