They promote: i) the oxidation of the sulphide matrix, rendering gold more accessible to the leaching solution; ii) gold stabilisation, a result of the formation of gold-rich complexes and/or colloids; and iii) gold solubilisation by enhancing the permeability of ore bodies (Amachi, 2008; Brehm et al., 2005; Burford et al., 2003; Hilson and ...

Heap Leaching of Gold and Silver Ores

Original sulfide content is typically 2–3% pyrite, and the gold is often enclosed in the pyrite. Oxidized ores yield 65–85% recovery but may have to be crushed to below 12 mm (½″), although some ores are successfully leached at run-of-mine sizes. Unoxidized ores yield 45–55% gold recovery and nearly always need crushing.

Dense Media Separation (DMS) Plants

The upper limit of the ore particle size is related to the ore size, embedding characteristics, and equipment size. In usually, the ore is 50-150mm, and the coal is 300-500mm. DMS can greatly reduce the surrounding rock and waste rock under the same processing capacity, reduce ore grinding consumption, thus reduce production costs.

Features, Types and Selection of Filter Press Feed Pump

The pressure is essential to force the liquid through the filter medium and form a filter cake of solids. Abrasion Resistance: Since filter press applications often involve abrasive slurries, the pump's components should resist wear and tear. Selecting hardened metals or abrasion-resistant coatings can help prolong the pump's life.
