Beneficiation process of gold ore
Gold beneficiation is a process that involves two and a half stages of closed-circuit crushing, followed by two stages of closed-circuit grinding and flotation. Afterward, the selection process involves sweeping the tailings away through rough sorting operations. The selected tailings and sweep are combined with ore concentrate for regrinding.
