[0002] Magnesite crystals are trigonal carbonate minerals, typically appearing as granular crystals or cryptocrystalline, dense blocks. The latter, also known as porcelain magnesite, is white or off-white, with iron-containing minerals appearing yellow to brown and possessing a vitreous luster. The processing of magnesite tailings requires the use of a calciner, a thermal process equipment that heat-treats carbonaceous raw materials (such as coke and anthracite) at high temperatures to improve their properties. These equipment is used for ironmaking, rare metal recovery, catalyst production, environmental improvement, and the production of specialty chemicals. However, current magnesite tailings calcining equipment lacks waste heat recovery, resulting in wasted heat energy and resources.
