13.5.1: Mineral Resources
Minerals must be concentrated into deposits to make their collection economically feasible. A mineral deposit containing one or more minerals that can be extracted profitably is called an ore. Many minerals are commonly found together (e.g. quartz and gold; molybdenum, tin and tungsten; copper, lead and zinc; platinum and palladium).

Review Iron oxide copper-gold (IOCG) deposits – A review …
Several workers have proposed broad definitions of IOCG deposits such that some iron oxide-rich deposits with little or no copper or gold are considered part of the IOCG 'family' as possible 'end-members' or as 'affiliated' deposits (e.g. Hitzman et al., 1992, Williams et al., 2005, Corriveau, 2007, Barton, 2013).

Gold deposits – where they can be found and why
The minerals found in the breccia zone and the fractures can be gold, copper, silver, and molybdenum, among other things. In the meantime, the intrusion of the magma body – that hot crystalline mush monster coming up from the Mantle – has caused the rocks above and around it to fracture and pulverize.

Intrusive related gold usually also contains copper, and is often associated with tin and tungsten, and rarely molybdenum, antimony and uranium. Intrusive-related gold deposits rely on gold existing in the fluids associated with the magma (White, 2001), and the inevitable discharge of thesehydrothermal fluids into the wall-rocks (Lowenstern, 2001).

The interaction of clay minerals with gypsum and its effects on copper
Six flotation tests were conducted using the copper–gold ore and its mixtures with quartz, clay minerals and gypsum. Fig. 1 shows the mass recovery as a function of water recovery from these tests. As can be seen, flotation of the ore or baseline resulted in a 5% mass recovery and 31% water recovery at the completion of flotation.

Conclusion. Pretty much all metals are minerals. But not all minerals are metals. As far as gold is concerned, it's a metallic mineral. Because the term "metal" is not as broad or all-embracing as the word "mineral", and because gold usually gets discussed in the same vein as other metals (copper, silver, platinum, etc.), the yellow metal invariably gets identified as …
