General Mining Process The mining process for metal extraction usually consists of two parts: mining and milling. The mining component is the extraction of metal-bearing ore from rock. The milling component generally crushes, grinds and extracts a concentrate in a series of mechanical and/or chemical processes. Figure 2.13 illustrates these two processes.
