The washing efficiency has a great influence on beneficiation. ④Water Power Ore Washing Screen. The ore washing method that uses water guns to wash on a fixed bar screen is used for easy-to-washGold usually occurs in these ores as discrete particulates (<0.1 µm in diameter) within sulfide minerals (mainly in pyrite and arsenopyrite) (Hausen, 1981; Radtke, 1985; Hausen et al., 1986; Wang et al., 1992, 1994). In gold ores, pyrite and arsenopyrite often occur in three morphological types: coarse, porous (blastic) and fine-grained.Establishing thE ProcEss MinEralogy of gold orEs SGS

The comparison of both the beneficiation methods for minerals indicates the more efficient recovery of potassium applying the chemical beneficiation method than the physical beneficiation method [31, 32]. The detailed discussion on the major potassium recovery process from different rocks and minerals is presented in Sect. 3.1.Gold recovery methods. Following leaching, gold ions remain dissolved in the solution, together with other elements. It is necessary to recover gold ions from this solution, separating them from the other dissolved metals present. This section of the paper reviews some of the most common methods used to recover gold from leaching solution. A systematic review of sustainable gold extraction from raw
