摘要
Collector compositions for use in froth flotation processes for the beneficiation of gold and silver values from base metal sulfide ores are disclosed. The collector compositions comprise at least one mercaptobenzothiazole compound selected from compounds of the formula: IMAGE wherein R is a C1-C8 alkyl or a C2-C8 alkoxy radical. The use of the substituted mercaptobenzothiazole collectors provides excellent metallurgical recoveries of gold and silver values in froth flotation processes conducted over a broad range of pH conditions including acid, neutral and mildly alkaline pH.
