Beneficiation - Wikipedia

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. The earliest practices of roasting were done outside, allowing large clouds of sulfur
