锌硫分离浮选新调整剂的研究

STUDY ON A NEW REGULATOR FOR ZINC-SULPHUR SEPARATING FLOTATION

车河选厂处理的矿石性质不断变化，锌精矿的选别指标波动较大，锌精矿品位仅为４２％～４３％，对原矿回收率在５０％～６０％范围内波动．针对生产上存在的问题，１９９４年以来进行了流程查定，找出锌金属的走向，堵塞住锌金属的流失，强化了锌金属的归队．在锌硫分离浮选作业中进行了新调整剂—氯化铵的工业试验，获得锌精矿品位４７．６８％，对原矿回收率８３．３９％的选别指标，

As properties of the ore treated in Chehe Mineral Processing Mill change constantly,the beneficiation results of Zn concentrate fluctuate significantly;the grade of Zn concentrate used to be 42%～43% and its recovery to the raw ore ranged between 50%～60%.Aiming at the problem existing in production, since 1994,the flow-process examination has been conducted for finding out the run of Zn metal,blocking Lip the loss of Zn and strengthening the oriented flow of Zn. The industrial test for applying a new regulatorammonium chloride in the Zn-S separating flotation has been conducted and beneficiation results that the grade of Zn concentrate is 47. 68% and its recovery to the raw ore is 83. 38%have been obtained.
