Feldspars - Used in manufacture of glass, ceramics and enamels. Includes orthoclase, microcline, and albite (member of the plagioclase series). Gemstones - The most valuable total gemstone production is diamond; corundum varieties, ruby and sapphire; beryl varieties emerald, aquamarine, and kunzite.

Gold extraction - Wikipedia

Gravity concentration has been historically the most important way of extracting the native metal using pans or washing tables. Amalgamation with mercury was used to enhance recovery, often by adding it directly to the riffle tables, and mercury is still widely used in small diggings across the world.

Mineral processing | metallurgy |

Mineral processing: Mineral processing, art of treating crude ores and mineral products in order to separate the valuable minerals from the waste rock, or gangue. It is the first process that most ores undergo after mining in order to provide a more concentrated material for the procedures of extractive metallurgy.

Extractive metallurgy - Wikipedia

Extractive metallurgy is a branch of metallurgical engineering wherein process and methods of extraction of metals from their natural mineral deposits are studied. The field is a materials science, covering all aspects of the types of ore, washing, concentration, separation, chemical processes and extraction of pure metal and their alloying to suit various applications, sometimes for direct ...

Uranium Enrichment | Enrichment of uranium - World Nuclear ...

Uranium Enrichment (Updated June 2018). Most of the 500 commercial nuclear power reactors operating or under construction in the world today require uranium 'enriched' in the U-235 isotope for their fuel.

Gravity Concentration | Gekko

Gravity concentration is the separation of minerals based on differences in specific gravity. A gravity concentration process is designed to recover very high grades of valuable ore material into very small masses.

Glossary of Mining Terms -

Demonstrated reserves — A collective term for the sum of coal in both measured and indicated resources and reserves. Deposit — Mineral deposit or ore deposit is used to designate a natural occurrence of a useful mineral, or an ore, in sufficient extent and degree of concentration to invite exploitation.

Specific gravity | physics |

Specific gravity is a related quantity that is defined as the ratio of the density of the analyte to the density of water at a specified temperature. The procedure used to measure specific gravity often employs an instrument called a hydrometer, which…
