Copper Ore Mineralogy | Bruker
Porphyry copper ore is challenging X-ray mineralogy. The mineralogy of the ore, concentrates and residues is complex. Twenty or more minerals are to be quantified in most of the samples. Peak overlap is massive and may mask minor phases. Clays and other layered material make a reproducible sample preparation difficult.
Mineral processing - Wikipedia
Crushing and grinding are the two primary comminution processes. Crushing is normally carried out on "run-of-mine" ore, while grinding (normally carried out after crushing) may be conducted on dry or slurried material. In comminution, the size reduction of particles is done by three types of forces: compression, impact and attrition.

Copper extraction - Wikipedia
Copper extraction refers to the methods used to obtain copper from its ores.The conversion of copper consists of a series of physical and electrochemical processes. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors.. As in all mining operations, the ore must usually be beneficiated (concentrated).
