| 摘 要： | 研究结果表明 ,金的浮选指标取决于金矿物在黄铁矿、脉石中的分布率和金的载体矿物黄铁矿的嵌布粒度以及脉石中金矿物的粒度。矿石氧化使黄铁矿变成褐铁矿也会影响浮选效果 ;金矿物与黄铁矿的解离程度影响金回收率 ;正常氰化条件下 ,金精矿磨得愈细 ,氰化渣含金愈低。该研究成果为优化浮选、氰化工艺条件提供了依据

| Abstract: | The study shows that the metallurgical performances of gold flotation depend on the distribution of gold minerals in pyrite and gangues, disseminated grain size of pyrite and size of gold minerals in gangues. Also, the oxidation of ore, changing pyrite into limonite, have an effect on gold flotation. The liberation degrees of gold minerals and pyrite affects gold recovery. At normal cyaniding, the finer the gold concentrate is ground, the lower gold content of leaching residue. |
