摘　　要：本文对某难选钼矿石进行了提高钼精矿品位的试验研究。查清了钼精矿品位低下的主要原因是可浮性好的被铁的氧化物染成红褐色的长石等脉石矿物的影响,针对这种现状,研究添加K-4抑制剂对钼精矿品位有显著提高。Experiments on improving molybdenum concentrate grade of a refractory molybdenum ore were carried out. The main cause of low molybdenum concentrate grade was ascertained, which is the influence of the gangue mineral with good floatability as feldspar that browned by iron oxide. In view of this situation, adding K -4 de- pressant to improve the molybdenum concentrate grade significantly was studied.
