摘要
本研究的矿石属高硫磁黄铁矿型矿石,闪锌矿和磁黄铁矿紧密共生,互相包裹,致使矿石十分难选。试验结果表明一段磨选浮磁联合工艺是从该矿石中选锌的有效途径,对诸如高硫多金属硫化矿矿石不宜采用阶段磨选流程。
The ore in this study is a high-sulphur pyrrhotite-type ore, where sphalerite is so cloesly associated and locked with pyrrhotie that it is very difficult to separate them from each other. Test results show that the combination separation technlogy of one-stage grinding, flotation separation and magneric separation is an effective way to separase zinc from the ore, and a stage-grinding circuit is not suitable for processing high-sulphur polymetallic ores.
