摘要
高氧化率辉钼矿的分选是选矿领域的难题,用常规浮选机浮选很难达到满意的效果。采用柱式分选工艺流程对河南某高氧化率辉钼矿进行了不同的流程试验,一次粗选两次精选流程对全粒级矿石分选,作业平均回收率为54.76%,钼精矿品位平均为29.08%,相比浮选机全流程作业回收率高出8.80%,钼精矿品位高10.31%。该法为氧化辉钼矿的分选做出了有益的探索。
High -oxidative molybdenite ore was a difficulty in mineral processing. Satisfactory resuits were hardly achieved to process it using the traditional floatation machines. Tests had been done to processing high - oxidative molybdenite in Henan by using cyclonic - static micro - bubble flotation column in this paper. A molybdenum concentrate with grade of 29.08% Mo and a recovery of 54.76% were obtained by the flotation column flowsheet consisting of one roughing and two cleanings when separating full size range of ores. Compared with the traditional flotation flowsheet, a molybdenum concentrate grade and recovery increased by 10.31% and by 8.80% respectively. This method was beneficial for the extending study on oxidative molybdenite ores.
