在矿石浮选中,氧化铅品位的高低对药剂的加入量以及回收率的计算等都极为重要。氧化铅含量低时,浮选药剂加入量过多,则会导致已活化好的铅,不易起泡而滞留在浮选机中,造成药剂与人力、物力资源的浪费,而氧化铅含量高时,浮选药剂加入量过少,则会导致矿物中的铅不易被选出,造成矿产资源的浪费。本文以闪锌矿为例,研究如何准确测定氧化铅,从而对企业浮选进行生产指导。 In the ore flotation, the level of lead oxide is very important for the dosage of the chemicals and the recovery calculation. When the content of lead oxide is low, too much flotation reagent can lead to activated lead which is not easy to foam and stay in the flotation machine, resulting in the waste of reagents and human and material resources. When the content of lead oxide is high , Flotation additives added too little, it will lead to lead in minerals is not easy to be elected, resulting in the waste of mineral resources. In this paper, sphalerite, for example, to study how accurate determination of lead oxide, and thus the production of enterprise flotation guidance.
