摘要:
新疆某辉钼矿含钼0.12 %、铜0.009 %，针对矿石中有微量的黄铜矿与辉钼矿连生的性质，为降低钼精矿含铜量，提高钼精矿品位与回收率，采用铜钼混选-粗精矿再磨-抑铜浮钼工艺流程进行了试验研究。结果表明：在试验获得的工艺参数下，得到的钼精矿钼品位49.55 %、钼回收率82.41 %；铜粗精矿含铜0.25 %、金2.45 g/t，铜、金回收率分别为89.85 %和63.12 %；原矿中0.14 g/t的金主要富集在铜粗精矿中。试验有效回收钼的同时，实现了对铜、金的综合回收。

Abstract:
A molybdenite in Xinjiang contains 0.12 % molybdenum and 0.009 % copper.In the case that a trace amount of chalcopyrite and molybdenite intergrow in the ore,to reduce the copper content in the molybdenum concentrate and improve the grade and recovery of molybdenum concentrate,the process of copper-molybdenum bulk flotation-rough concentrate regrinding-copper inhibition and molybdenum flotation was studied by experiment.The results show that with the process parameters obtained in the test,the grade of the molybdenum concentrate obtained is 49.55 %,the molybdenum recovery rate is 82.41 %;the rough copper concentrate contains 0.25 % copper and 2.45 g/t gold,and the copper and gold recovery rates are 89.85 % and 63.12 % respectively;the 0.14 g/t gold in raw ore is mainly enriched in the rough copper concentrate.While the experiment effectively recovers the molybdenum,copper,and gold are comprehensively recovered.
