摘　　要：通过检测发现多数锡石硫化矿中的有用矿物存在着致密共生状态,而单独的重选是不能将硫化物去除,且多数密度较大的硫化矿物如黄铁矿、黄铜矿、闪锌矿、磁黄铁矿等中去除硫化物正是保留锡的关键,因此需要在重选之前或者之后,再通过使用浮选的方式进行脱硫,进而获得锡石精矿。Most useful minerals in cassiterite sulfide ore exist in a dense symbiosis state,and the removal of sulfide from most sulfide minerals with large density such as pyrite,chalcopyrite,sphalerite,pyrrhotite,etc.is the key to retain tin.Gravity separation alone cannot remove sulfide,so it is necessary to desulfurize by using flotation before or after gravity separation to obtain cassiterite concentrates.
