在浮选含有易浮脉石的多金属硫化矿时,易浮脉石会造成严重的不良影响。我们在某铜锌硫多金属硫化矿的浮选试验中采用羧甲基纤维素抑制易浮脉石获得较好的结果。 (一) 矿石性质该矿是沉积变质加热液改造为特点的铜锌硫多金属硫化矿。金属矿物主要为黄铁矿,次为磁黄铁矿、闪锌矿,及少量的黄铜矿、铜兰等;脉石矿物为滑石、透辉石、绿泥石、绢云母、透闪石、蛇纹石等。
Pumice stones can cause serious adverse effects when they are flotated for polymetallic sulphide minerals that are easily paralyzed. We use carboxymethyl cellulose in the flotation test of a Cu, Zn-S polymetallic sulphide ore to obtain good results for the inhibition of easily floating paraffin. (A) the nature of the ore The deposit is a metamorphic hydrothermal fluid transformation of copper and zinc sulfur polymetallic sulfide ore. Metallic minerals are mainly pyrite, pyrrhotite, sphalerite, and a small amount of chalcopyrite, copper blue, etc .; gangue minerals are talc, diopside, chlorite, sericite, tremolite , Serpentine and so on.
