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 .
The magnesium smelter in Bécancour, Quebec used to be operated by Norsk Hydro, [3] and was shuttered by 2011. [2] The Dominion Magnesium Limited smelter in Haley Station, Ontario was the site for the first industrial implementation of the Pidgeon process. It began operation around 1942 and ceased operation before 2010. [2]
Magnesium hydroxide is an inorganic compound with the chemical formula Mg(OH) 2. It occurs in nature as the mineral brucite . It is a white solid with low solubility in water ( K sp = 5.61 × 10 −12 ). [ 5 ]
The price slump lasted until 2004 which saw a price surge that had copper reaching $9,000 per tonne in the May 2006, but it eventually fell down to $7,040 per tonne in early 2008. [93] When the slump came, it hit some copper mining countries like the Democratic Republic of the Congo (D.R.C.) very hard.
Calcium magnesium acetate (CMA, with chemical formula C 12 H 18 CaMg 2 O 12 [1]) is a deicer and can be used as an alternative to road salt. It is approximately as corrosive as normal tap water , and in varying concentrations can be effective in stopping road ice from forming down to around −27.5 °C (−17.5 °F) (its eutectic temperature ...
Vapor-deposited magnesium crystals from the Pidgeon process. The Pidgeon process is a practical method for smelting magnesium.The most common method involves the raw material, dolomite being fed into an externally heated reduction tank and then thermally reduced to metallic magnesium using 75% ferrosilicon as a reducing agent in a vacuum. [1]
Crystalline magnesium oxide, or periclase, has a calculated lattice energy of 3795 kJ mol-1 which must be overcome for it to go into solution or for reaction to occur. Reactive magnesia is essentially amorphous magnesia with low lattice energy and is made at low temperatures and finely ground.
