摘　　要：某地区锰矿床中含锰10.22%的低品位尾矿渣,为提高该锰矿资源的利用率,对其进行阳离子反浮选试验。结果表明在固定条件为粒度-0.074 mm的矿样占97.63%,矿浆浓度为20%,捕收剂十二胺用量为0.5 kg/t,调整剂硫酸用量为3.0 kg/t,捕收剂糊精用量为1 kg/t和柠檬酸用量为2 kg/t,经过“一粗二精、一次粗选和一次闭路”试验,可获得锰品位20.91%、回收率为69.51%的锰精矿,显著地提升了锰资源的综合利用效率。In order to improve the utilization rate of manganese ore,the cationic reverse flotation test was carried out for the low-grade tailing slag containing 10.22%manganese in a manganese ore deposit in a certain area.The results show that the pulp concentration,in the“0.074 mm(97.63%),is 20%in 12 amine collector dosage of 0.5 kg/t.The adjusting agent dosage of sulfuric acid is 3.0 kg/t,and collector dosage of dextrin is 1 kg/t in citric acid dosage of 2 kg/t”fixed condition.In an“a-rough selection,a-second selection,a-sweep selection and a-closed circuit”test,available manganese ore concentrate grade 20.91%and recovery was 69.51%,as significantly improves the efficiency of the comprehensive utilization of manganese resources.
