Martin Marietta Production of Magnesium Hydroxide and Magnesium Oxide. In a synthetic magnesia process, naturally occurring brine is mixed with both dolime and water to produce an aqueous suspension containing magnesium hydroxide and calcium chloride: CaCl 2 + MgCl 2 + H 2 O + (CaO•MgO) + 2H 2 O —> 2Mg(OH) 2 + 2CaCl 2 + H 2 O. CaCl 2 + MgCl ...

Abstract. Thermochemical equilibrium calculations indicate the possibility of considerable fuel savings and CO{sub 2} emission avoidance in the three steps of the Pidgeon process: (a) calcination of dolomite; (b) production of ferrosilicon from quartz sand, coal, and iron oxide; (c) silicothermic reduction of calcined dolomite by ferrosilicon to magnesium.

The proposed process basically combines two decades old processes (Solvay and Dow Magnesium) for the manufacture of soda ash and magnesium, respectively into a single process that also produces "partially-desalinated" water. It does so by subjecting salt brines first, to ammonia causing two simultaneous actions: 1) the absorption of ammonia forming what is called "ammoniated brine ...

3.1.2 Basic Principles of Pidgeon Process. Calcined dolomite is the most remarkable raw material to use as magnesium source in the Pidgeon process and, it theoretically contains 58.2 mass% CaO and 41.8 mass% MgO, respectively. 6 The fundamental principle of the Pidgeon Process is the reduction of magnesium from calcined dolomite by using silicon (or any silicon containing material like ...

3.4.1) Electrolytic Processes Electrolytic processes have dominated production magnesium from the 1970s to 1990s. In general, these processes include feed preparation, dehydration of magnesium chloride and electrolysis (Habashi, 1997). The process involves two stages: a) Production of pure magnesium chloride from sea water or brine b ...

Example process flow diagram for furnace injection of magnesium hydroxide slurry. Magnesium hydroxide slurry is available as a commercial product, or it can be produced onsite at plants that are equipped with a Thiosorbic lime FGD system and have a process to convert the calcium sulfite by-product to gypsum.

The present invention relates to a process for the production of potassium chloride and of magnesium chloride hexahydrate (bischoffite) from carnallite or from carnallite containing sodium chloride. The process comprises heating carnallite at a temperature of between above 70° C. and above 167.5° C. in the presence of added water at the above former temperature or without added water (but ...
