Flash calcination of a magnesite ore in a free-fall

Oct 01, 1994 Introduction Magnesite ore is the primary source for production of magnesium compounds. The natural magnesite contains impurities such as silicon, iron and calcium which effect the quality of products. Therefore, these impurities must be removed from the ore. For this purpose, some physical and chemical benefication methods are used.

Magnesium (Mg) is a silvery white metal that is similar in appearance to aluminum but weighs one-third less. With a density of only 1.738 grams per cubic centimetre, it is the lightest structural metal known. It has a hexagonal close-packed (hcp) crystalline structure, so that, like most metals of this structure, it lacks ductility when worked at lower temperatures.

{The wet high intensity magnetic separation of magnesite

Chemical composition of magnesite ore is complex and varies from region to region. Depending on the source, it contains MgO (42-47 %), CaO (1.0-2.0 %), SiO 2 (1 %), Al 2 O 3 (1 %), Fe 2 O 3 (1 %) and 50 % mass loss on ignition. Depending on the magnesia content, magnesite ores can be classified into three groups as high (MgO > 46 %), middle and low
