Magnesium, ready for war uses in February 1943. Production of this lightest of all metals, vitally needed in the United Nations' war effort, is increasing daily at Basic Magnesium's giant plant in the southern Nevada desert. A 24-hour production schedule results in the turning out of thousands of ingots ready for shipment to aircraft and tracer ...

By 2011 magnesium production had departed under the Kyoto Protocol from Canada. [4] Wu, Han and Liu bragged that "China is the world’s largest producer of primary magnesium and has a magnesium smelting industry that is mainly based on the Pidgeon process" in an era in which China had obtained an 80% market share of production of magnesium ...
Also in 2014, Nevada Clean Magnesium announced its Tami-Mosi plan to create a ASTM B-92 pilot plant. The mineral resource is estimated at 412 billion tons of 12.3% grade Mg. [ 8 ] The company produced its first ingot from a pilot plant in December 2018.
Magnesium oxide (Mg O), or magnesia, is a white hygroscopic solid mineral that occurs naturally as periclase and is a source of magnesium (see also oxide). It has an empirical formula of MgO and consists of a lattice of Mg 2+ ions and O 2− ions held together by ionic bonding .
Lloyd Montgomery Pidgeon, OC MBE (December 3, 1903 – December 9, 1999) was a Canadian chemist who developed the Pidgeon process, one of the methods of magnesium metal production, via a silicothermic reduction. [1] He is considered the "father" of academic metallurgical research in Canada. [2] [3] [4]
The production of magnesium was extremely dangerous due to its volatility. Just as production was ramping up in August 1941, three men were killed as a blaze erupted when powdered magnesium was funneling through a rubber coupling into a cylindrical retort. [41] In November 1941, another worker was burned when a reduction retort flared up.
Fritz Johann Hansgirg (1891–1949) was an Austrian electrochemist and metallurgist who in 1928 invented a carbothermic magnesium reduction process. [1] In 1934, he left Austria for the Empire of Japan where he worked with industrialist Shitagau Noguchi to set up a magnesium plant, and then helped build a pilot plant to produce heavy water using a combined electrolysis catalytic exchange ...
