Cyanide leaching process is one of the common gold ore beneficiation processes. The process index depends on factors such as gold particle size, sulfide content, ore block size, leaching speed, leaching time, cyanide concentration and leaching slag washing degree. The factors that affect gold leaching include grinding fineness, pH, temperature, cyanide dosage, …

gold processing - gold processing - Mining and concentrating: The nature of the ore deposit determines the mining and mineral processing techniques applied. Oxide ore deposits are frequently of such low grade (e.g., 3 to 10 parts per million) that extensive mineral processing cannot economically be justified. In this case they are merely shattered by …

With the increase of the grinding fineness, the gold leaching rate increases first and then slowly. It can indicate that increasing the grinding fineness is beneficial to release of gold minerals from the inclusions. Take into comprehensive consideration, a 325 mesh accounted for 95% is a more suitable gold leaching grinding fineness.

The gold in refractory gold ores is usually wrapped in sulfide minerals in the form of fine particles. It is difficult to dissociate the gold monomer by the usual fine grinding (p80 = 53-75um). In the process of gold leaching, the leaching agent can not contact with gold, resulting in low recovery rate of gold and no economic value.

As to the use of hammer mills for fine crushing of the ore, I would have some issues of the mills causing a flattening of the particles which can cause loss of gold in gravity processes as the gold will not settle at the rate you expect.
