(Horst 1985, p. 3A5). Average grinding sizes for the ore can be brought down to 1015 microns at the very most, if using long grinding periods on a product which has already passed a 200 mesh sieve. Some specific mills are reported to be available, which are capable of grinding the ore down to sizes of 5 microns or less.

Formation of minerals | Britannica

Minerals are usually formed by inorganic processes. Synthetic equivalents of various minerals, such as emeralds and diamonds, are manufactured for commercial purposes. Although most minerals are chemical compounds, a small number (, sulfur, copper, gold) are elements. Minerals combine with each other to form rocks.

Nevada Bureau of Mines and Geology

Metals are taken from the rocks of an ore deposit using chemistry. In processing ore to recover the metal of interest, steps of the process can be divided into (a) the steps to prepare the metal for separation from the rest of the rock or other metals, and (b) steps to actually remove the metal from the rock and unusable or uninteresting parts ...

Mineral processing | Metallurgy, Crushing Grinding | Britannica

mineral processing, art of treating crude ores and mineral products in order to separate the valuable minerals from the waste rock, or gangue. It is the first process that most ores undergo after mining in order to provide a more concentrated material for the procedures of extractive metallurgy.
