平桂冶炼厂精选车间是一个集重选、磁选、浮选于一体,选矿设备较为齐全、选矿工艺灵活多变的精选厂。随着平桂矿区锡矿资源的枯竭,精选厂大部分时间处于停产状态,企业的生产和经济效益受到严重影响。虽然进行了氧化矿精选尾矿的综合回收,取得了一定的经济效益,但远不能满足经济发展的需要,硫化矿精选尾矿还没有得到综合利用。为了更充分地利用矿产资源,综合回收多种有价金属,充分利用现有的闲置设备,增加企业的经济效益,我们进行了锡石-硫化矿精选尾矿的多金属综合回收试验,并根据试验研究情况组织生产,产出了锡品位为34.5%、回收率为35.20%的锡精矿及锡品位为2.60%、回收率为15.60%的锡中矿和砷品位为28%、回收率为65%的砷精矿,取得了较好的效益。
Pinggui Smelter Workshop is a selection of re-election, magnetic separation, flotation in one, more mineral processing equipment, processing technology, flexible selection plant. With the depletion of the tin ore resources in Pinggui Mining Area, most of the selected plants are in shutdown status, and the production and economic benefits of the enterprises are seriously affected. Although comprehensive recovery of tailings from oxide ore has been carried out and some economic benefits have been obtained, it is far from meeting the needs of economic development and the comprehensive utilization of tailings from sulfide ore has not yet been fully utilized. In order to make full use of mineral resources, comprehensively recover a variety of valuable metals, make full use of existing idle equipment, and increase the economic benefits of enterprises, we conducted a comprehensive trial of polymetallic recovery of tailings from cassiterite-sulfide ore. According to the experimental research, the production of tin concentrate and tin with the grade of 34.5%, the recovery rate of 35.20% and the grade of tin with tin of 2.60% and the recovery rate of 15.60% and 28%, respectively, the recovery rate 65% of the arsenic concentrate, and achieved good results.
