铜陵是我国铜矿重要产地之一。矿床中除主元素Fe、Cu、S外,尚有V、Ti、Co、Ni、Au、Ag、Pt、Ga、Ge、T1、I、Cd等二十余种伴生元素。随着国民经济的发展,有益伴生组分的综合利用成了日益重要的课题。 天鹅抱蛋山硫铁矿矿床富含硫、金、铜。其中伴生金的储量已达大型矿床,有着重要的经济价值。 本次工作查明了金的赋存状态,金的载体矿物为磁黄铁矿,细粒金占86％,金的平均品位为2.97g/T。经数理统计等方法,金与砷成正相关关系。金与其它矿物间的连生关系较复杂,接触边界弯曲,所以该矿属难解离类型。 据研究结果可得出结论:该矿不适宜重选,可用混合浮选或氰化和混汞法以提高金的回收率。
Tongling is one of the most important copper mines in China. In addition to the main elements of the deposit Fe, Cu, S, there are more than 20 kinds of accompanying elements such as V, Ti, Co, Ni, Au, Ag, Pt, Ga, Ge, T1, I, With the development of the national economy, the comprehensive utilization of beneficial associated components has become an increasingly important issue. Swan Eggshan pyrite deposits rich in sulfur, gold and copper. Associated gold reserves have reached a large deposit, which has important economic value. This work identified the presence of gold, gold carrier minerals pyrrhotite, fine grain accounted for 86%, the average grade of gold is 2.97g / T. By mathematical statistics and other methods, gold and arsenic is a positive correlation. The symbiotic relationship between gold and other minerals is more complicated and the contact boundary is curved, so the ore is difficult to separate from the type. According to the results of the study, it can be concluded that the mine is not suitable for re-election, and mixed flotation or cyanidation and amalgamation methods can be used to increase gold recovery rate.
