1996/1/1· Bauxite deposits are essentially old soils and occur in a variety of geological and geomorphic situations. They are classified as: 1) lateritic bauxite deposits underlain by alumino silie rocks, they are products of “in-situ” tropical weathering 2) Karst bauxite deposits cover the uneven, karstified surface of limestones and dolomites 3) Tikhvin-type deposits.

Shortage of raw materials // REMONDIS Sustainability

Reserves of bauxite are estimated to be 28,000 million tonnes and resources to be 65,000 million tonnes. There is no firm data about the production and reserves of gallium. However, by taking the data that is available and assuming that 95% of gallium is obtained from bauxite, it is possible to give a rough estimate of the gallium reserves and resources as well as to calculate its static lifetime.

Strategic Materials - The World Factbook

Silicon carbide (SiC) is a synthetic mineral most commonly produced in electrical resistance furnaces by the Acheson process. A mixture of carbon material (usually petroleum coke) and either silica or quartz sand is reacted at high temperatures (1,700 – 2,500°C) resulting in the formation of α-SiC.

In metallurgy, a non-ferrous metal is a metal, including alloys, that does not contain iron (ferrite) in appreciable amounts. Generally more costly than ferrous metals, non-ferrous metals are used because of desirable properties such as low weight (e.g. Aluminium), higher conductivity (e.g. copper), non-magnetic property or resistance to corrosion (e.g. zinc).
