Product Use |
Magnesium carbonate, also known as magnesite, is a mineral that is primarily sourced from underground deposits or extracted from seawater. The production of this mineral involves a series of steps, including extraction, purification, and dehydration.
Extraction: Magnesium carbonate is commonly extracted from magnesite ore, which is a rock composed mostly of magnesium carbonate. The ore is usually mined through open pit or underground mining methods. Once the ore is extracted, it is then crushed and ground into a fine powder.
Purification: The extracted magnesium carbonate is then purified through a process called flotation, where impurities are separated and removed from the mineral. This process involves the use of chemicals and flotation agents.
Dehydration: The purified magnesium carbonate is then dehydrated through a process called calcination. This involves heating the mineral at high temperatures to remove any remaining water and create a more concentrated form of magnesium carbonate.
