res four methods for gold recovery: amalgamation, cyanide leaching, a shaking sluice, and Cleangoldmsluic The results show that a combination of manual panning or Cleangoldmsluices followed by cyanidation is the best solution under present condi-tions, followed by cyanidation alone Based on the knowledge obtained, remarks on...
For sulfide ores, a different process is taken for beneficiation The ore needs to have the sulfur removed before smelting can begin Roasting is the primary method of separating, where wood was placed on heaps of ore and set on fire to help with oxidation 2 Cu 2 S + 3 O 2 → 2 Cu 2 O + 2 SO 2...
