摘要:
根据宜昌磷钾矿的矿物特性,以TSM-46、十二胺为捕收剂,碳酸钠、硫酸作为pH调整剂,水玻璃作为抑制剂与分散剂,对宜昌磷钾矿进行了一次粗选一次扫选的小试实验,并对富钾尾矿进行了浮选,获得了适宜的粗选工艺参数. 实验证明,在磨矿细度-0.074 mm质量分数 92.5%、浮选温度50 ℃、碳酸钠用量8.5 kg/t、水玻璃用量4 kg/t、粗选捕收剂TSM-46用量粗选2 kg/t、扫选0.8 kg/t的条件下,磷精矿品位为15.17%,回收率达74.47%;在十二胺用量0.2 kg/t,矿浆pH 1.8的条件下,钾精矿品位为11.05%,回收率达45.09%.
Abstract:
Floatation of phosphate-potassium associated ores from Yichang was carried out with single-stage roughing and single-stage scavenging process according to the mineralogical characteristics of the ores. TSM-46 and dodecyl amine, sodium carbonate and sulfuric acid, sodium silicate were used as collector, pH regulator and depressor, respectively. The grade and recovery of phosphate concentrate could reach 15.17% and 74.47%, in the conditions of grinding fineness of -0.074 mm 92.5%, flotation temperature of 50 ℃, sodium carbonate of 8.5 kg/t, sodium silicate of 4.0 kg/t, and TSM-46 of 2 kg/t for roughing and 0.8 kg/t for scavenging. The rich potassium tailing was floated in the conditions of dodecyl amine of 0.2 kg/t and pH value of pulp of 1.8. The result shows that the grade and recovery of potassium concentrate could reach 11.05% and 45.09%, respectively.
