grinding and gold leaching of iron ore

Use of dry grinding process to increase the leaching

The cyanide leaching behavior of roasted gold ore in different iron oxide pulps was studied by related scholars (Bas et al., 2015a; Bas et al., 2016; Bas et al., 2015b). They found that the gold leaching rate increased by 25% and 10% in hematite and maghemite pulp, respectively, whereas in magnetite pulp, the leaching rate of gold decreased by 40%.get price
