埃利—马桑铜—锌矿床的矿石,总储量约为7500千吨,铜含量1.32%,锌5.71%,金1.23克/吨,银44.09克/吨。主要有用矿物是:黄铜矿、闪锌矿、黄铁矿,含有少量的方铅矿、黝铜矿、金和银碲化物,还有一定数量的自然金和次生铜矿物。从1979年起,该矿山进行了采矿准备工作。制备了10—12吨试样,供美国科罗拉德矿业技工学校作可选性研究之用。选矿厂设计流程包括:三段破碎开路循环工作的棒磨机和装有水力旋流器闭路循环工作的球磨机磨碎矿石,两段调节——主要浮选。主要铜精矿经三次精选然后浓缩。粗选尾矿进行锌浮
The ore of the El-Massang copper-zinc deposit has a total reserves of about 7,500 tons, a copper content of 1.32%, zinc of 5.71%, gold of 1.23 g / t and silver of 44.09 g / t. The main useful minerals are: chalcopyrite, sphalerite, pyrite, a small amount of galena, tetrahedrite, gold and silver telluride, as well as a number of natural and secondary copper minerals. Since 1979, the mine has been prepared for mining. 10-12 tons of samples were prepared for optional research by the Colorado School of Mining and Technology. The design process for the concentrator includes: three stages of rod mill with broken open circuit and a ball mill with closed cycle hydroclone to grind the ore, two stages of conditioning - the main flotation. The main copper concentrate is concentrated three times and concentrated. Rough tailings zinc float
