    Aug 17, 2014 Due to its unstable and highly reactive nature, magnesium is refined through the process of electrolysis, whereby it is separated and extracted from its ore or solute form. A metallic object which violently reacts in contact with water and acids, magnesiums physical and chemical composition enforce the need for magnesium ores or seawater solution to be extracted through electrolysis..Magnesium is extracted from its ores by one of two processes. In the first, the ore is converted to magnesium chloride MgCl2, which is then electrolyzed.

    improve the flotation performance of separating dolomite from high magnesium phosphate ores. Three surfactants, diethyl phthalate DP, Tween-80 TW and derivative of sulfonate salt DSS1 were used. Hallimond cell flotation was conducted using pure dolomite.previous research reported the separation of manganese and magnesium ions utilizing ammonia solution and carbon dioxide or ammonium bicarbonate 18. More recently, PAKARINEN and PAATERO 19 also reported that carbonate precipitation is a fast and effective approach for manganese recovery and iron separation from sulfate solutions, with Na2CO3 or

Other ways to concentration minerals include approached based on density Froth Flotation used if ore density is less than density of impurities, or via melting points, or magnetic ....The extraction of magnesium mainly falls into two groups, i.e. electro-refining for magnesite and thermal reduction process for dolomite. Brief introduction will be given in the following passage. Thermal reduction process is represented by Pidgeon process, named after its inventor Dr. Lloyd Montgomery Pidgeon. Pidgeon process consists of four stages including calcination of the dolomite,

Chromite is found as orthocumulate lenses of chromitite in peridotite from the Earths mantle. It also occurs in layered ultramafic intrusive rocks. In addition, it is found in metamorphic rocks such as some serpentinites..Feb 01, 2014 Separation of magnesium and impurities in leachate liquor2.3.3.1. Two-step selective precipitation. A portion of preweighed leachate liquor was neutralized with lime milk to a certain pH end point at 45 C. After 1 h for further settling and precipitation of ferric hydroxide, the suspension was filtered. The filtered leachate designated as leachate a was neutralized with lime milk again to a pH endpoint of around 10.0 to recover the magnesium as the
