It is found in the ore xenotime ytrium phosphate, YPO4. Hydrometallurgical techniques such as heap leaching (HL), atmospheric leaching (AL), high-pressure sulfuric acid leaching (HPAL), Caron process, and direct nickel process (DNi) are the most common processes to treat lateritic ore 4. Cobalt is a ferromagnetic metal and is used primarily. Laterite ore contributes to about 70 of the world’s land-based nickel resources. The trihydroxide Co(OH) 3 is heated to form the oxide and then reduced with carbon (as charcoal) to form cobalt metal. It is found in the Earths crust at a concentration of 30 ppm, making it the 29th most abundant element. New Caledonia produced approximately 1,600 metric tons of cobalt in 2019 from its rich lateritic nickel ore deposits, which are noteworthy for their cobalt byproduct. Cobalt produces brilliant blue pigments which have been used since ancient times to color paint and glass. Iron is obtained by precipitation with lime (CaO) while cobalt is produced as the hydroxide by precipitation with sodium hypochlorite (NaOCl)ĢCo 2+(aq) + NaOCl(aq) + 4OH -(aq) + H 2O → 2Co(OH) 3(s) + NaCl(aq) Treatment with sulphuric acid leaves metallic copper as a residue and disolves out iron, cobalt, and nickel as the sulphates. Normally the ore is "roasted" to form a mixture of metals and metal oxides. Industrially, however, it is normally produced as a byproduct from the produstion of copper, nickel, and lead. Together with molybdenum, it is used in hydrodesulfurization catalysts for. These include the sulphides and arsenides linnaeite, Co 3S 4, cobaltite, CoAsS, and smaltite, CoAs 2. 27 Atomic Weight: 58.933195 (5) Melting Point: 1768 K (1494C, 2722F) Boiling Point: 3200 K (2926C, 5300F) Density: 8. In the chemical industry, cobalt is an essential constituent in important catalysts. Many ores contain cobalt but not many are of economic importance. Isolation: it is not normally necessary to make cobalt in the laboratory as it is available readily commercially.
