The conclusive step in gold mining was the milling of the raw ore. The ore dug out of the hard-rock mines needed to be crushed, the precious metal had to be chemically separated from the host rock, then recovered from the chemical. Early on, because the technology available did not allow for it to be completely refined,

Ball mills have been the primary piece of machinery in traditional hard rock grinding circuits for 100+ years. They are proven workhorses, with discharge mesh sizes from ~40M to <200M. Use of a ball mill is the best choice when …
One type of grinding mill commonly used in hard rock gold mining is the ball mill. This cylindrical device rotates around its axis and uses steel balls or other grinding media to pulverize the ore inside it. The rotation of the drum causes these balls to cascade and grind down the ore particles, resulting in a fine powder ready for extraction. ...
The product of these two stages of crushing and screening then passes to secondary milling. In hard-rock metals mining applications, HPGRs are currently in use in tertiary and quaternary crushing applications, as well as in secondary pebble crushing. In many respects, HPGRs replace crushers as a unit operation. However, from a process standpoint.
