LITHIUM carbonate is produced by lithium concentrate through roasting, acidification, filtration, purification, concentration, PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC and other processes, according to the purity of the product is divided into industrial grade lithium carbonate and battery grade lithium carbonate. Lithium deposits can be divided into five types, namely pegmatite deposits, brine deposits, seawater deposits, hot spring deposits and accumulated deposits. At present, the lithium resources exploited are mainly pegmatite deposits and brine deposits.
Spodumene: a monoclinic crystal system, often in the shape of broken columns, plate output, also seen granular dense block or granular, broken columns aggregate. Color black, green, ink, dark green or brown; Glassy luster, translucent to opaque; Hardness 5~6, density 3.15~3.6g/cm³. The monoclinic spodumene converts to the tetragonal high temperature spodumene at 720℃, the volume increases by 30%, and the iron is removed by PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC field.
Lithiolase: the appearance is similar to quartz, and it is transformed into high temperature spodumene at 700℃, and the iron is removed by PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC. Lithophosphorite: similar in nature to spodumene, soluble in sulfuric acid, although high in lithium, but less mineral resources.
