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 ...

The 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.

Crushing is the process of size reduction of ore. Size reduction process begins with usage of explosives at the area for production of ore. In later stages, the size reduction process performed with crushers before grinding in mills is called "crushing". Although there is no limit set, the downsizing process over 3 mm is considered as "crushing ...

Since there are not that many small SAG mill operations of under 2000 TPD, and most sub2000 TPD mills are built with rod mills and/or ball mills only; the upstream crusher plant needs to have sufficient crushing power to provide a P80 to grinding of typically <″ (40 mm) and often as finely crushed as <3/8″ (9 mm).

Step 1: Milling When ore enters the plant from underground it first needs to be milled to reduce its size so that the gold is liberated from the host rock. South Deep's milling circuit consists of a singlestage semiautogenous grinding mill (SAG) and a pebble crusher for primary milling, followed by secondary milling using two overflow ball mills.
