Gravity separation played an important role in gulch-gold production. Flotation method was widely used in rock gold mine[3]. No matter gravity separation or flotation, the ore must be ground very fine. In this way, in the process of sedimentation, concentration and dehydration of fine gold ore, the problem of slow sedimentation due to fine ...

Magnesium Extraction from Magnetic Separation Tailings of Laterite Ore
The composition of low-grade laterite ore from Yuanjiang, Yunnan, China was tested by chemical analysis. Under 7% of CaF 2 for the adjuvant agent and 8% of anthracite for the reducing agent, the main metal nickel and iron in laterite ore (100 g) can be efficiently recovered after high temperature (1250 °C) reduction. The process is shown …

Reading: Ore Genesis | Geology
Ore genesis theories are dependent on the mineral or commodity. Ore genesis theories generally involve three components: source, transport or conduit, and trap. This also applies to the petroleum industry, which was first to use this methodology. Source is required because metal must come from somewhere, and be liberated by some process.
