摘要
针对煤系硫铁矿精矿含碳较高不利于焙烧制酸的问题,为了有效利用煤系硫铁矿,以云南某高碳煤系硫铁矿石为试验矿样进行了降碳提硫研究。试验结果表明,采用K-1药剂为新的选碳捕收剂,利用反浮选脱碳和选择性絮凝手段,可以有效降低硫精矿碳含量,同时提高硫精矿品位。试验采用反浮选—正浮选—选择性絮凝流程,得到了硫品位为37.19%、含碳量为3.64%的煤系硫铁矿精矿,硫回收率为87.37%。
In view of the high carbon content in the coal-derived pyrite which is unfavorable for making acid, research on carbon reduction and sulfur lift was carried out using a high carbon coal-derived pyrite ore from Yunnan as test sample in order to efficiently utilize the coal-derived pyrite. The test results show that the carbon content in the sulfur concentrate can be effectively reduced meanwhile the grade of sulfur concentrate be improved by using K-1 reagent as the new collector for carbon and the reverse flotation and selective flocculation for decarbonization. The test adopted reverse flotation-selective flocculation flowsheet and obtained a coal-derived pyrite concentrate having a salfur grade of 37.19% , carbon content of 3.64% and sulfur recovery of 87.37%.
