摘要: 为了提高程潮铁矿磁选尾矿中铜、硫的回收率与精矿品位,针对磁选尾矿中铜、硫呈 细粒分散、可浮性差且易泥化等问题,进行了系统的浮选工艺试验。试验结果表明:条件试验确定 的最佳药剂制度为混合浮选粗选乙基黄药用量 90 g/t,起泡剂 2# 油用量 18 g/t;铜粗选采用石灰调节 矿浆 pH 值,石灰用量 2 800 g/t;铜精选采用活性炭对铜粗选精矿产品进行脱药,活性炭用量 45 g/t, Z-200 用量 4 g/t;最终闭路试验获得了铜品位 17.37%、铜回收率 76.26% 的铜精矿,硫品位 46.70%、 硫回收 86.23% 的硫精矿,显著提高了磁选尾矿中铜、硫的回收效率与精矿品位,为程潮铁矿尾矿资 源化利用提供了可行的工艺方案与理论依据。

Abstract: In order to improve the recovery rate and concentrate grade of copper and sulfur in mag⁃ netic separation tailings of Chengchao Iron Mine,a systematic flotation process test is carried out to solve the problems of fine particle dispersion,poor floatability and easy slime of copper and sulfur in magnetic separation tailings.The test results show that the optimum reagent system is determined by the condition test as follows: the dosage of ethyl xanthate in mixed flotation is 90 g/t,the dosage of foaming agent 2# oil is 18 g/t.Lime is used to adjust the pH value of pulp in copper roughing,and the dosage of lime is 2 800 g/t. Activated carbon is used to remove the reagent from copper rough concentrate products in copper cleaning. The dosage of activated carbon is 45 g/t,and the dosage of Z-200 is 4 g/t.In the final closed-circuit test, copper concentrate with copper grade of 17.37% and copper recovery rate of 76.26% is obtained,and sul⁃ fur concentrate with sulfur grade of 46.70% and sulfur recovery rate of 86.23% is obtained. The recovery efficiency and concentrate grade of copper and sulfur in magnetic separation tailings are significantly im⁃ proved,which provides a feasible process scheme and theoretical basis for the resource utilization of Chengchao iron ore tailings.
