辉钼矿中大量Al2O3、Si O2的存在不仅会影响辉钼矿浮选的效果,同时也增加了冶炼环节的能耗。为了降低这个影响,在辉钼矿浮选单因素实验的基础上,通过1段粗选、1段扫选、6段精选的开路实验流程,使用混合抑制剂最终得到钼精矿品位40.23%,回收率57.36%,钼精矿中Al2O3品位4.31%,回收率1.68%,Si O2品位14.25%,回收率0.94%。 The presence of a large amount of Al2O3 and Si O2 in the molybdenite not only affects the flotation effect of molybdenite, but also increases the energy consumption of the smelting process. In order to reduce this influence, based on single-factor experiment of flotation of molybdenum ore, through the open experimental procedure of roughing, cleaning and selecting of 6 sections, the molybdenum concentrate grade was 40.23% , The recovery rate is 57.36%, the molybdenum concentrate has the Al2O3 grade of 4.31%, the recovery rate of 1.68%, the Si O2 level of 14.25% and the recovery rate of 0.94%.
