magnesium ore extraction

Magnesium: extraction-Metalpedia

Magnesium: extraction. Brife introduction. Magnesium is found in solution in sea-water (about 1.3 kg m-3 magnesium) and in natural brines. It is also found extensively in the ores magnesite (MgCO3) and dolomite (MgCO3.CaCO3). Both of the two types of resources can be used as raw materials to manufacture magnesium metal.

Experimental and Kinetic Study of Magnesium Extraction

2019-1-29  Overall, the extraction rate of magnesium increased as a function of time and reached a maximum at 120 min. Figure 3c shows the extraction rate as a function of the molar ratio (ammonium sulfate to ore) of reactants. It shows that a higher molar ratio benefitted the magnesium extraction; when the molar ratio was greater than 2 : 1, the extraction rate plateaued.

How Is Magnesium Extracted? Blurtit

Answer (1 of 2): "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. In the second process, the ore is convertedto magnesium oxide (MgO), which is then treated with the alloy ferrosilicon. The ferrosilicon reacts with magnesium oxide to yield pure magnesium metal."
