Abstract: For some roasted pyrite slag from Anhui province , studies was made applying several process, including single gravity separation , single magnetic separation , spiral chute -shaking ta-ble separation , two-stage magnetic separation -shaking table separation process , and two-stage magnetic separation -spiral chute separation joint process .The experimental results show that u-sing the preliminary screening -two stage magnetic separation -shaking table separation joint process , an iron concentrate assaying 62%TFe was obtained with a recovery of 76 .49%, and with S content less than 0 .30%.The study provides a technical basis for the comprehensive utilization of the slag.
