Magnesium Info [MarZ Chemistry]
Occurrence, uses, and properties. It also is found as the hydroxide (brucite), chloride (carnallite, KCl MgCl2 6H2O), and sulfate (kieserite). Magnesium is commercially produced chiefly by the electrolysis of molten magnesium chloride and by the thermal reduction of magnesium oxide with ferrosilicon (see magnesium processing ).

CARNALLITE (Hydrated Potassium Magnesium Chloride)
The crystals will unfortunately absorb water from humid air (a process called deliquescence). This process can be eased by storing specimens in sealed dry containers. Carnallite is an important source of potash, an invaluable fertilizer. Sylvite is the more important source of potash, but carnallite makes a significant contribution. Carnallite's magnesium output is of much lesser importance world wide but is .

To that purpose, leaching experiments with Mg solutions were performed in laboratory columns filled with two types of acid soil materials differing largely by their organic carbon content : g C kg1 for soil A and g C kg1 for soil B. Magnesium was supplied either as a solution saturated in dolomite or as a pulse of kieserite solution.

Zinc processing Ores |
In this process, the ore initially is crushed to about centimetres ( inch), combined with water, and ground to less than millimetre in a ball mill. The finely ground particles and water form a slurry that flows from the mill to flotation cells or tanks, where, in the presence of selected chemical reagents that create a suspension of air bubbles, the slurry is agitated by beaters.

Agricultural Lime vs. Dolomite Lime
When to Use Aglime or Dolomite. Before you can even begin to think about whether agricultural lime or dolomite could benefit your soil, you first need to have an understanding of when these materials are actually necessary. Aglime and dolomite both become useful when soil becomes too acidic.

Precipitated Calcium Carbonate (PCC) is produced through a recarbonisation process or as a byproduct of some bulk chemical processes. Dolomite fillers are also produced from indigenous stone, similar to GCC, but as the UK has no viable source of high whiteness dolomite rock, again this material is also imported but processed locally by a few BCCF member companies.

Magnesium is extracted in one of three ways. The first is the electrolytic process, which uses magnesium chloride produced from magnesite or seawater. The second is the silicothermic process, which mixes calcined dolomite or magnesite with ferrosilicon alloy. The third involves dissolving magnesite in hydrochloric acid to make magnesium chloride.
