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.

MAGNESIUM PRODUCTION FROM ASIAN ABE-GARM …

In the Pidgeon Process, magnesium metal is extracted from calcined dolomite under vacuum and at high temperatures using ferrosilicon as a reduci ng agent [1]. In this process, the finely crushed dolo mite is feed into kilns where it is calcined. The calcin ed dolomite is then pulverized in a mill prior to mixi ng with finely ground ferrosilicon.

How Is Magnesium Metal Produced?

Extraction from Dolomite and Magnesite Ore. Electrochemical processes are used to extract the metal from dolomite and magnesite ore. When dolomite is crushed, roasted and mixed with seawater in large tanks, magnesium hydroxide settles to the bottom. Heating, mixing in coke, and reacting with chlorine, then produces molten magnesium chloride.

Which metal ore is a dolomite? - Quora

Answer (1 of 3): Dolomite is a common rock-forming mineral. It is a calcium magnesium carbonate with a chemical composition of CaMg(CO3)2. It is the primary component of the sedimentary rock known as dolostone and the metamorphic rock known as dolomitic marble. Limestone that contains some dolomi...

What is Dolomite? Dolomite, also known as "dolostone" and "dolomite rock," is a sedimentary rock composed primarily of the mineral dolomite, CaMg(CO 3) 2.Dolomite is found in sedimentary basins worldwide. It is thought to form by the postdepositional alteration of lime mud and limestone by magnesium-rich groundwater.. Dolomite and limestone are very similar rocks.

In England, dolomite has become a useful source for the production of magnesite by reacting calcined dolomite with sea-water. The UK is meeting nearly 50% of her magnesite requirements by this method. Dolomite is also a good source of magnesium metal. The magnesium metal is extracted from dolomite by the well-known fero-silicon process.

Dolomite is also used as a source of magnesium oxide for making magnesium metal and for chemical uses, such as the common laxative milk-of-magnesia. Dolomitic limestone's and dolomites are mined along with limestone and used for crushed stone and aggregates for manufacture of pavement, concrete for construction and as fill material.

However, the tin concentrate grade of 40% is required, meaning the enrichment of hundreds or thousands times. Targeting at the refractory tin ore, low grade tin concentrate is obtained and it has to be further extracted by special metallurgy process. Reduction smelting is the dominant process to extract tin metal from tin concentrate.
