extraction of magnesium from dolomite

Extraction of magnesium from calcined dolomite ore using

Dolomite is one source of magnesium besides seawater. The extraction of magnesium from dolomite ores can be done by leaching process. In this work, the dolomite leaching to extract magnesium by hydrochloric acid was investigated. The leaching experiments were performed in a spherical glass batch reactor having a capacity of 1000 ml. The effects of the stirring speed, acid concentration,

Magnesium: extraction-Metalpedia

Step 1: Dolomite ore is crushed and heated in a kiln to produce a mixture of magnesium and calcium oxides, a process known as calcining: Step 2: The next step is reduction of the magnesium oxide. The reducing agent is ferrosilicon (an alloy of iron and silicon) which is made by heating sand with coke and scraps iron, and typically contains about 80% silicon.

Thermal decomposition of dolomite and the extraction of

01/10/1997· More than 92% of the CaO available for extraction in dolomite can be recovered in a single cycle using strictly controlled procedures. The basic magnesium carbonate obtained from the aqueous solution is of pharmaceutical grade purity (less than 1% total impurities), having Ca as a major contaminant. All other elements such as AI, Fe, K, Si, etc. are only present in trace quantities. More

magnesium processing Techniques & Methods Britannica

In the latter method, exemplified by the IG Farben process, lightly burned dolomite is mixed with seawater in a flocculator, where magnesium hydroxide is precipitated out, filtered, and calcined to magnesium oxide. This is mixed with charcoal, formed into globules with the addition of magnesium chloride solution, and dried. The globules are charged into a chlorinator, a brick-lined shaft furnace where they are
