我厂硫化矿车间的原矿来自松树脚锡矿,属于锡石多金属硫化矿、主要目的矿物是锡石,并综合回收铜、锌、钨、铋、硫、萤石等有价矿物.生产采用浮-重原则工艺流程,浮选采用混合-优先浮选流程,获得铜精矿品位9～11%、回收率77～80%;硫精矿品位32%、回收率78%的选别效果.铜、硫精矿的产值为该车间生产总值的30%左右.本文仅就该类矿石铜的选矿实践,谈
The ore of our sulfide ore plant comes from the pine foot tin ore and belongs to the cassiterite polymetallic sulphide ore. The main purpose mineral is cassiterite and the valuable minerals such as copper, zinc, tungsten, bismuth, sulfur and fluorite are comprehensively recovered. Float - heavy principle of the process, flotation using the mixed - priority flotation process, to obtain the copper concentrate grade 9 ~ 11%, the recovery rate of 77 to 80%; 32% sulfur concentrate grade, the recovery rate of 78% of the sorting effect. The output value of copper and sulfur concentrate is about 30% of the total production value of this workshop.
