All About Particles: Modelling Ore Behaviour in Mineral …
Comminution is the process of reducing the particle size of an ore to liberate the ore minerals from the gangue minerals. Thus, comminution strongly controls the overall efficiency of a mineral processing operation. Even though blasting as the first step of extracting an ore from the ground is also a form of comminution, the focus here

Gold Process Equipment
Gold Ore Mining. Placer gold mining mainly refers to mining from the land surface or river or underground. It mainly uses gravity separation because its density is much bigger than other minerals. Compared with placer gold, rock gold ore has higher gold content and mining value, but the beneficiation process of rock gold ore is much more complicated than that of placer gold ore.

Direct Smelting: An Alternative to Mercury Use in Gold Mining
In over 80 developing countries in the world, mercury is the artisanal gold miner's go-to for separating gold from concentrated ore. Due to a lack of resources and available alternatives, mercury is often handled with bare hands, and in the effort to amalgamate gold, much of it escapes into waterways and soil where it enters the food chain.

8.2 Mining and Ore Processing – Environmental Geology
A typical ore body will contain a few percent of ore minerals—typically sulphide minerals like chalcopyrite or sphalerite—along with the minerals of the original rock (e.g., quartz, feldspar, amphibole etc.). Most ores also contain some other non-ore minerals (e.g., hematite) and some other sulphide minerals, especially pyrite (FeS 2).
