Anode carbon residue is produced in the production of electrolytic aluminum. Its properties need to be studied for secondary utilization. In this paper, mineralogy of anode carbon slag from an electrolytic aluminum plant in Guizhou was studied , the anode residue chemical composition, structure, mineral composition, occurrence state of main elements, etc, was investigated, the results show that: Anode carbon residue is mainly composed of 14 minerals such as cryolite, cryolithionite, elpasolite and graphite. Among them, the opaque minerals are mainly graphite and the transparent minerals are mainly cryolite. Carbon in the form of independent mineral occurrence in graphite, fluoride in the form of independent mineral occurrence in cryolite, cryolithionite, elpasolite and fluorite, aluminum in the form of independent mineral occurrence in cryolite, cryolithionite, elpasolite, aluminium oxide and magnesium aluminate, sodium in the form of independent mineral occurrence in cryolite, cryolithionite, elpasolite. The mineralogical characteristics and occurrence state of carbon and electrolyte were studied, which provided a basis for the separation and recovery of carbon and electrolyte in anode carbon residue.

电解铝阳极残炭中碳和电解质的存在状态

电解铝生产过程中会产生阳极残炭。需要对其性质进行研究以进行二次利用。本文以贵州某电解铝厂阳极炭渣的矿物学为研究对象，对阳极残渣化学成分、结构、矿物组成、主要元素赋存状态等进行了研究，结果表明：主要由冰晶石、冰晶石、elpasolite和石墨等14种矿物组成。其中，不透明矿物以石墨为主，透明矿物以冰晶石为主。石墨中独立矿物形式的碳，冰晶石中独立矿物形式的氟化物、冰晶石、elpasolite和萤石中形式的氟化物，冰晶石中独立矿物形式形式的铝，冰晶石、elpasolite、氧化铝和铝酸镁、钠以独立矿物形式存在于冰晶石、冰晶石、elpasolite中。研究了碳和电解液的矿物学特征和赋存状态，为阳极残炭中碳和电解液的分离回收提供了依据。
