·4H2O under a suitable H2SO4 acidity,which can lessen the product concentration,continue the hematite dissolution and improve the iron removal rate. A reasonably higher temperature during curing process leads to a higher iron removal rate. The pretreatment works effectively. For calcine containing Fe of 31.25%(mass fraction) and Au of 84.27 g/t,the gold leaching rate reaches 97.51% and the residual......
