摘　　要：由于滑石和辉钼矿具有相似可浮性,辉钼矿和滑石的浮选分离成为回收滑石型钼矿中钼的关键.文中研究了不同种羧甲基纤维素(CMC)对于滑石和辉钼矿的不同抑制能力,探明了CMC的特性和不同生产原料对于其抑制滑石和辉钼矿能力的影响,为选取更高效浮选分离滑石和辉钼矿的CMC做出了探索性研究.Due to the similar floatability of talc and molybdenite, separation of these two minerals via flotation is the key element for recovering molybdenum from talcose molybdenite. Different depressing abilities of several types of Carboxymethyl Cellulose （CMC） from different resources were studied to investigate the influences of CMC＇s characters on their depressing ability, providing the exploratory research for choosing more effective CMC for the flotation separation of molybdenite from talc.
