Dolomite's chemical name is calcium magnesium carbonate [CaMg(CO3)2]. Magnesium is extracted from it.
Nov 24, 2019· 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.
Alginate is an anionic polysaccharide extracted from brown algae commonly used in biomedical, bioprocessing and pharmaceutical applications. Its mild ionic gelation makes it an attractive hydrogel for the encapsulation of cells and tissue engineering. So, this month the Dolomite team has been looking at producing alginate beads using microfluidics!
McKenzie decided to test the idea experimentally. She extracted bacteria from the Red Lagoon and mixed them into a simulated sludge consisting of sand, nutrients, sulfate, and all the ingredients for making dolomite. Then she put the mixture into a refrigerator.

Apr 11, 2020· Magnesium is extracted in one of three ways. The first is the electrolytic process, which uses magnesium chloride produced from magnesite or seawater. The second is the silicothermic process, which mixes calcined dolomite or magnesite with ferrosilicon alloy. The third involves dissolving magnesite in hydrochloric acid to make 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.

Up to this dose, excess dolomite was present, and the acid completely reacted with the dolomite. Increasing the extract dose to 3.6 mL caused the pH to decrease rapidly to pH 2.34 (from pH 4.92 at an extract dose of 3.4 mL). This indicated that there was an excess of acid when the dose was 3.6 mL, and all of the dolomite reacted.
Dolomite, type of limestone, the carbonate fraction of which is dominated by the mineral dolomite, calcium magnesium carbonate. Along with calcite and aragonite, dolomite makes up approximately 2 percent of the Earth's crust. Learn more about the structure, properties, and uses of dolomite in this article.
Dolomite is a common mineral, typically found in a wide variety of rocks. It is the main component of dolostone, a type of sedimentary rock. As a mineral, dolomite is used in agriculture, where its ability to neutralize acid makes it a key ingredient in specialty fertilizer and soil conditioner.
