- W2393451569 abstract "First,floatation recovery is done in the test for pyrite,and influences on the three factors,slurry mass concentration,pH,HD floatation chemical consumption on the floatation process are discussed,and the optimum floatation conditions are obtained: slurry mass fraction is 20%,pH is 8.5,HD floatation chemical consumption is 200 g/t,w(S) is 29.48% in fine sulfur ore,w(S) is reduced to 1.13% in the tailing.After desulfurization,tailing at the bottom will be removed of carbon and organic matters using high-temperature calcination,and it is determined that the optimum calcination temperature is 750 ℃,calcination duration is 2 h,and after calcination,chemical method is used to remove the iron in the tailing.The optimum consumption of strong reducing agent on the iron removal through reduction are ascertained.And the primary kaoline with whiteness of 64.8% is obtained in the test." @default.
