Gold milling, which is also known as fine grinding, pulverising or comminution, is a grinding process that reduces materials into a powder or finer sized particles. Milling is used to recover the maximum amount of gold from the ore by finely grinding it so that gold particles can be removed through gravity separation and/or chemical extraction.

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 single-stage semi-autogenous grinding mill (SAG) and a pebble crusher for primary milling, followed by secondary milling using two overflow ball ...
Copper processing begins with mining copper ore, which contains less than 1% of copper, and ends with sheets of 99.99% pure copper (cathodes). Copper mining generally takes place through open-pit mining, in which a series of stepped benches are dug deeper into the earth. Yet, it can also be mined underground, through horizontal tunnels.
