摘要:

随着矿山资源的不断枯竭,如何实现矿石资源的最大化利用已成为当前矿山企业面对的重要课题。许多氰化厂生产过程中产生的氰化尾渣含有多种有价元素,具有很高的回收利用价值。因此,本次研究以有价金属的最大化回收为例,现阶段对于各氰化厂氰渣中的部分有价金属(如金、银和铅等)进行回收,通过添加特种药剂,包括各种调整剂、分散剂、捕收剂和起泡剂等浮选药剂的合理联合应用,利用浮选的方法,采用一次粗选、两次扫选、三次精选的浮选流程,最终获得了铅品位>20%、回收率>50%银品位>330 g/t及金品位>9 g/t的优质铅精矿,大幅提升了氰渣的利用率,并产生了巨大的经济效益,对同类矿山企业有着较强的借鉴意义。

Abstract:

Along with the mine resource is dried up,in current,the reality subject of mining enterprise facing is how to maximize the utilization of mineral resources.A lot of cyanide residue which produced in cyanidation plant contains a variety of valuable elements,and these elements have high recycling value.Therefore,the research is to the maximize valuable metal recovery for the direction and the present stage of the cyanide residue in cyanide plant,containing part of valuable metals such as gold,silver and lead by adding special agents,including reasonable combination application of various regulator,dispersant,collector and frother.Using flotation method of a roughing,two times of scavenging and three times of cleaning flotation process,and finally got the quality lead concentrate of the lead grade greater than 20%,the recovery rate of greater than 50%,silver grade of more than 330 g/t and the gold grade of more than 9 g/t. In this way,the utilization rate of cyanide residue has been greatly enhanced and the huge enormous conomic benefit has been produced.From a certain meaning,this research has a stronger referential significance for the same type of mining enterprises.

Key words: Flotation, Valuable metal, Low grade, Cyanide residue, Au, Ag, Pb
