前言目前,全世界开采出来的锡矿石绝大部分都呈锡石存在。采用重选工艺富集锡石虽是简单、经济、且回收率较高的手段,但因其共生的金属矿物总是与锡石一道,在重选中富集。所以,几乎所有重选选出的锡石粗精矿都要精选分离。大多数脉锡矿是很复杂的。对锡石多金属硫化矿而言,为了使锡石 Foreword At present, most of the tin ore mined in the world is in the form of cassiterite. The use of re-election process cassiterite is a simple, economical, and high recovery means, but because of its symbiotic metal minerals are always together with cassiterite, enrichment in the re-election. Therefore, almost all of the re-election of cassiterite concentrate should be carefully selected separation. Most vein pulse tin is very complicated. For cassiterite polymetallic ores, in order to make cassiterite
