8.2: Mining and Ore Processing
Relatively deep deposits, or those with elongated or irregular shapes are typically mined from underground with deep vertical shafts, declines (sloped tunnels) and levels (horizontal tunnels) (Figures 8.2.1 and 8.2.2). In this way it is possible to focus the mining on the orebody itself. In some cases, the near-surface part of an orebody is ...Web

What Is Mineral Processing in Mining?
The screening process. The smaller ore will go on to the ball grinding mills where they will be further ground down. The larger ore will be routed to a pebble crusher to reduce the size to 1.3 cm (½ in) and will return to the SAG mill stage. The ball mill product is pumped to cyclones which separate out the coarse material with the fine ore.Web
