Metallic Deposits - CliffsNotes

Metallic Deposits. Metals occur in all kinds of rocks but usually in concentrations that are too low to be mined. Metallic ore deposits, however, are relatively rare concentrations of metal‐bearing minerals (usually sulfides) that contain enough metal to be profitably mined. Again, the profit line is dependent on a number of economic factors.

9 Ore Deposits and Economic Minerals – Mineralogy

The best metal ore minerals are those that contain large amounts of metals of value. Most metallic ore minerals are native elements, sulfides, sulfosalts, oxides, or hydroxides. Ore deposits are highly variable in nature and origin. The most important kinds of ore deposits are magmatic, hydrothermal, or sedimentary. 9.1 Mineral Commodities

ORE DEPOSIT TYPES AND THEIR PRIMARY EXPRESSIONS K.G ...

PRIMARY EXPRESSIONS OF ORE DEPOSITS A well known aspect of ore deposit expression is the association of particular ore types with particular host rock assemblages, i.e., the ore-host rock association (e.g., Stanton, 1972). This association broadly reflects the geological environment and processes that have formed the ore.
