| 中文摘要: |
| 国外某金矿属于毒砂型金矿，原矿含金3.25 g/t，金主要微细颗粒形态赋存于黄铁矿及毒砂中。采用浮选方法对该金矿进行提取预富集，浮选回收的主要目的矿物为含金黄铁矿及毒砂，经济合理地提高目的矿物的解离度及采用选择性良好的捕收剂是强化回收目的矿物的有效手段，通过工艺流程及药剂制度的优化，最大化提高预富集精矿中金的回收率。 |
| 英文摘要: |
| A foreign gold ore which exist in arsenopyrite, containing 3.25 g/t of gold, most gold was hosted in pyrite and arsenopyrite as fine particles form. Gold was enriched by flotation methods, the main purpose mineral of flotation recovery was pyrite and arsenopyrite. Improve the objective mineral degree of dissociation by economy and reasonable methods and using good selectivity collectors are effective methods to recover objective minerals. improve the gold recovery rate of concentrate by optimize the technical process and reagents system. |
