Summary:The invention relates to the technical field of mineral separation, and particularly discloses a beneficiation method for gathering fine precious metals through colloid strengthening. The beneficiation method for capturing the fine precious metal comprises the steps that a reducing agent and sulfuric acid are added into manganese ore pulp for stirring and leaching, and a primary leaching system is obtained; adding a composite coagulation agent into the primary leaching system, and then continuously stirring and leaching to obtain a secondary leaching system; and the secondary leaching system is subjected to solid-liquid separation, and acid leaching liquid and acid leaching residues containing precious metal are obtained respectively. The method provided by the invention can realize effective recovery of the bound noble metal in the manganese mineral. 本发明涉及矿物分选技术领域,具体公开了一种胶体强化捕集微细贵金属的选矿方法。本发明提供的捕集微细贵金属的选矿方法,包括步骤:向锰矿矿浆中加入还原剂和硫酸进行搅拌浸出,得到一次浸出体系;向一次浸出体系中加入复合聚沉药剂,之后继续搅拌浸出,得到二次浸出体系;二次浸出体系进行固液分离,分别得到酸浸液和含贵金属酸浸渣。本发明方
