对用选择性浮选法从铜精矿中分离钼的工艺进行了研究。该工艺过程包括从低品位钼焙砂的浸出液中用湿法分离铜和钼。它的主要优点是提高了钼的回收率、降低了辉钼矿的临界焙烧温度以及提高了产品纯度。本文还对不同的浸出和分离方法进行了研究。最有前途的方法是,于温度120～140℃、压力0到10巴共有元素硫存在的条件下,在高压釜中对培砂进行氨假选择性浸出。此时,钼进入适于直接沉淀的高浓度溶液中,其相应的流程如图1所示。
The process of separating molybdenum from copper concentrate by selective flotation was studied. The process involves the wet separation of copper and molybdenum from leachate of low grade molybdenum calcine. Its main advantages are increased molybdenum recovery, lower critical calcination temperature of molybdenite and improved product purity. The paper also studied different leaching and separation methods. The most promising method is to carry out ammonium pseudo-selective leaching of sand in an autoclave at a temperature of 120-140 ° C and a pressure of 0 to 10 bar in the presence of elemental sulfur. At this point, molybdenum into high-concentration solution suitable for direct precipitation, the corresponding process shown in Figure 1.
