Magnesium procurement

It is not always possible to get good quahty water for the industry from the local sources. The raw water may contain salts of calcium, magnesium, sodium etc. These can canse both temporary as well as permanent hardness. It may also contain floating imprrrities, dissolved solids, organic impurities like chlorides, sulphates, dissolved oxygen etc. This water needs to be treated before it can be used in the process or for cooling dnties etc. Otherwise it can spoil the final product quality due to insoluble matter, cause corrosion of equipment, waste the fuel due to formation of scales in boilers, npset process conditions due to scales in the cooling jackets and so on. Hence, it is essential to procure a water treatment plant or create the facility in-house. 

While procurement of most chemicals was usually a simple commercial transaction, in the case of some half-dozen real complications arose. This half-dozen included hexachlorocthane for smoke mixture, thermite, barium nitrate, barium chromate, magnesium for incendiary bombs, and chlorine. ... 

Immediately after the Pearl Harbor attack, the Under Secretary of War directed the Chief of the Chemical Warfare Service to "take all measures necessary to expedite so far as possible the delivery of incendiary bombs. In January 1942 the OC CWS, after hearing from the War Production Board that magnesium would be available by May or June, notified each of five procurement district offices to arrange for the purchase of components of the M50 bomb. The district offices began immediately to negotiate contracts for components and for casting magnesium bomb bodies. 

In this study focused on magnesium contained in dolomite, which can be procured in Japan, and evaluated fluorine removal performance and analyzed removal mechanism.
