The Mining Process. Gold at Macraes is known as 'refractory ore', which means it is ultrafine and resistant to the typical cyanide leach process. The mining process at Macraes is circular and follows a cycle of exploration, mining, processing and rehabilitation and closure. With a 30year history of development spanning fluctuating gold ...
WhatsApp: +86 18838072829The first comminution stage in a mineral processing plant is crushing, which reduces the size of particles from up to 1 m down to cm (depending on the type of milling circuit). Crushing is typically a dry process that makes use of Gyratory, Jaw, and Cone crushers (NapierMunn et al., 1996), which predominantly make use of impact mechanism.
