摘　　要：本文针对河南某地高硫铝土矿进行反浮选脱硫试验研究,铝土矿中的硫含量超标会直接影响氧化铝生产指标,因此,为解决河南某高硫铝土矿的开发利用问题,进行了反浮选脱硫试验。试验确定的磨矿细度为-0.074 mm占80%,SNS用量为1000g/t,硫酸铜用量100g/t,ZBD用量600g/t,经1粗4精反浮选开路流程处理,铝土矿精矿中硫含量降至0.30%,满足氧化铝生产要求。In this paper,a high sulfur bauxite in Henan province was studied by reverse flotation desulphurization test.The sulfur content in bauxite exceeds the standard will directly affect alumina production index.Therefore,in order to solve the development and utilization problem of a high sulfur bauxite in Henan Province,reverse flotation desulphurization test was carried out.The grinding fineness determined by the test is 80%-0.074 mm,SNS dosage is 1000 g/t,copper sulfate dosage is 100 g/t,ZBD dosage is 600 g/t,the sulfur content of bauxite concentrate is reduced to 0.30%by one roughing and four cleaning reverse flotation open circuit process,which meets the requirements of alumina production.
