摘要/Abstract

摘要： 某铜矿重介质产品铁品位56.24%，硫含量高达9.34%，95.72%的硫以磁黄铁矿的形式存在。为获得硫含量<2%的铁精矿，按磨矿—弱磁选—浮选原则流程对该矿石进行了选矿试验。试验结果表明，在最佳试验参数下，重介质产品经一段磨矿（-0.043 mm 85%）—1粗1精弱磁选—1粗2扫脱硫浮选流程处理，可获得产率45.23%、硫含量为1.52%、全铁品位66.50%的铁精矿，可作为后续钢铁冶炼原料的配矿使用，为此类重介质产品的利用提供技术参考。

Abstract: The iron grade of a copper mine′s heavy medium product is 56.24%,the sulfur content is as high as 9.34%,and 95.72% of sulfur is in the form of pyrite.In order to obtain the iron concentrate with sulfur content lower than 2%,the ore was processed according to the principle of grindinglow intensity magnetic separationflotation.Experimental results show that under the optimum parameters of the test,heavy media products after one stage grinding (-0.043 mm 85%) one roughing one cleaning low intensity magnetic separationone roughing two scavenging desulfurizing flotation process processing,iron concentrate with production rate of 45.23%,sulfur content is 1.52%,total iron grade of 66.50% can be obtained,can be used as raw materials for the subsequent steel smelting of ore matching,which can provide technical reference for utilization of such heavy medium product.
