Heating, mixing in coke, and reacting with chlorine, then produces molten magnesium chloride.


The present invention provides a method for extracting magnesium from dolomite that significantly reduces the cost of separating magnesium. A dolomite is obtained by reacting a dolomite with an aqueous solution of a water-soluble calcium salt having a solubility in water at 20 C. of 5 g / 100 g-H 2 O or more to extract magnesium in the dolomite as a magnesium ion-containing aqueous solution.


Extraction efficiency was tested on bulk samples, clay samples, pure celestine, and barite purchased from W. Niemetz (Servitengasse 12, 1090 Vienna, Austria); pure dolomite powder from Alfa Aesar (Thermo Fisher – Kandel – , P.O.

Oxidation of Hydrobromic acid to Bromine 1:Oxidation Of Bromide to Bromine Seawater is acidified using H2SO4. ( pH8-3.5). Why? At High pH Chlorine and Bromine react with Water.

Using high

Aug 24, 2016The injection of modified seawater or low-salinity water increased the oil recovery from carbonate and sandstone reservoirs (McGuire et al. 2005).Low-salinity water gave better recovery than seawater because of the low salt concentration of the low-salinity water (Morrow et al. 1998; Tang and Morrow 1999a; 1999b; 1997).Lowering the salinity or total dissolved solids (TDS) of the injected water

Mineral Resources from the Ocean

Magnesium, dissolved in sea water at a concentration of about 1,000 parts per million, is the only metal directly extracted from sea water. Presently, approximately 60 percent of the magnesium metal and many of the magnesium salts produced in the United States are extracted from sea water electrolytically.

Dolomite and dolomitization model

Dolomite types On the basis of the mode of formation, dolomites can broadly be divided into two groups: primary dolomite and secondary dolomite.2 Primary dolomite precipitate directly from aqueous solution, mostly at or near room temperature (20-35oC), with no CaCO 3 dissolution involved.3 However, dolomite can also form as a secondary phase

Seperation of dolomite from manganese

Dolomite also serves as an oil and gas reservoir rock During the conversion of calcite to dolomite a volume reduction occurs This can produce pore spaces in the rock that can be filled with oil or natural gas that migrate in as they are released from other rock units This makes the dolomite a reservoir rock and a target of oil and gas drilling.
