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

Oct 30, 2019 The flotation process is also used to treat polymetallic gold-bearing ores such as gold-copper, gold-lead, gold-bismuth, gold-copper-lead-zinc-sulfur ore. For this type of ore, the flotation process can effectively select various gold-bearing sulfide concentrates, which is conducive to the comprehensive recovery of mineral resources.
Selective attachment processes in ancient gold ore
This Roman gorse process was an extraordinarily successful method for ancient gold ore beneficiation and was the first technical application of superhydrophobicity in a submerged state. Today, superhydrophobicity is primarily used for water-repellant coatings.
