我厂是一个处理铅锌铜多金属矿的小型选矿厂。原矿的性质比较复杂,品位相差也很悬殊。为适应这种情况,我厂采取了以下两种方法。 (一)进行合理配比,处理不同矿石由于矿石的产地不同,各种矿石的可浮性差异较大。对这种情况,我们对不同类型的矿石进行搭配试验。在广西冶金研究所的帮助下,对难浮选分离和易浮选分离的矿石配比选矿,取得了较满意的结果。难选矿石的产品质量由绝大部分等外品上升为4—5品级,产品回收率提高4～6％。这为我厂从外地购进矿石,以满足生产需要开辟了一条路子。 (二)工艺流程灵活我厂的工艺流程是部分混合浮选,铅铜混合浮选是一粗四精三扫,锌流程
Our factory is a small concentrator dealing with lead, zinc and copper polymetallic ore. The nature of the ore is more complex, the grade difference is also very poor. In order to adapt to this situation, I plant the following two methods. (A) a reasonable ratio to deal with different ore Due to the different origin of ore, a variety of ore floatability differences. In this case, we test the different types of ores. With the help of Guangxi Institute of Metallurgy, the ore beneficiation benefited from the separation of flotation-free and flotation-flotation was more satisfactory. Refractory ore product quality from the vast majority of other products rose to 4-5 grade, product recovery rate increased by 4 to 6%. This is my factory purchased ore from the field, to meet the needs of production has opened up a way. (B) flexible process I plant is part of the mixed flotation process, lead-copper mixed flotation is a coarse four fine sweep, zinc flow
