为了提高伴生贵金属的回收率可应用能与铂族金属形成牢固络合物的辅助捕收剂,如可以混合应用离子型捕收剂(如丁基黄药)和非离子型捕收剂(异丙基硫代氨基甲酸酯)或用环状三硫代碳酸盐改性的黄药。为了提高ДМДК的作用效果和降低其用量,建议采用以下措施:在黄药前添加ДМДК;使进入镍与磁黄铁矿分离作业给矿中的黄铜矿数量降到最低;优化铜浮选回路中的硫代硫酸盐的用量,使进入镍-磁黄铁矿分离回路中硫代硫酸盐数量最低。
In order to increase the recovery rate of the associated precious metal, auxiliary collectors capable of forming a strong complex with the platinum group metal, such as ion-type collectors (such as butyl xanthate) and non-ionic collectors Propylthiocarbamate) or xanthate modified with cyclic trithiocarbonate. In order to improve the effect of ДМДК and to reduce its dosage, the following measures are recommended: ДМДК before the xanthate; to minimize the number of chalcopyrite into the ore from the separation of nickel from pyrrhotite; to optimize the copper flotation circuit The amount of thiosulfate present minimizes the amount of thiosulfate entering the nickel-pyrrhotic separation loop.
