The Grinding Fineness- the Factor Affecting Gold Leaching

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, …

The size of the particles is an important parameter as a large grain of a gangue mineral (e.g., quartz) behaves like a small grain of gold in a classic gravity separation process. The rate at which a particle settles in a liquid depends on the particle weight and the viscosity of the liquid (in this case the pulp of ore).
