The process can be used with a variety of steels, bronzes, and aluminum alloys. With machinable materials, the process is still useful if the gear is integral with some complicated shape that is very difﬁcult to produce by machining. Large quantities of small, low-cost gears are made by the cold chamber die casting process
The Bayer Process was invented and patented in 1887 by Austrian scientist Karl Josef Bayer. Two to three tonnes of bauxite are required to produce one tonne of alumina. 90% of the global alumina supply of around 90 million tonnes is used in aluminium production.
The patent-protected technology was developed by Alcoa and is currently producing metal at the Alcoa Technical Center, near Pittsburgh in the United States, where the process has been operating at .
In 2017, China was the top producer of aluminium with almost half of the world's production, followed by Russia, Canada, and India. Although aluminium demand is rapidly increasing, known reserves of its bauxite ore are sufficient to meet the worldwide demands for aluminium for many centuries.
An important component of metal accounting is reconciliation. This is done by ensuring that two sets of records are in agreement at the end of a reporting period and discrepancies are readily identified and addressed. In mining, this reconciliation process applies to .
ANFO has found wide use in coal mining, quarrying, metal mining, and civil construction in undemanding applications where the advantages of ANFO's low cost and ease of use matter more than the benefits offered by conventional industrial explosives, such as water resistance, high detonation velocity, and performance in small diameters.
