The cobalt hydroxide obtained by the second precipitation of cobalt contains about 50% of water, is blended with a small amount of petroleum coke, and is sintered into a porous cobalt oxide agglomerate in a reverberatory furnace, and then with a desulfurizing agent CaO, a reducing agent (petroleum coke) and a slag forming agent SiO 2 . charged with an electric furnace smelting at high temperature, reduction and interpolation wet wood stirring, the cobalt oxide is reduced to cobalt metal, and removing impurities, casting cobalt-containing more than 95% of the crude cobalt anode plate, for cobalt electrowinning Refined. There are three purposes for the reverberatory furnace calcination: (1) dehydrating and decomposing cobalt hydroxide, converting it into cobalt oxide, and sintering into a porous agglomerate; (2) adding petroleum coke to semi-reducing cobalt oxide; (3) Removal of some sulfur. Reverberatory furnace available coal, coal gas, liquefied petroleum gas, natural gas or heavy oil as fuel. Jinchuan Company uses heavy oil as fuel and uses low-pressure nozzles, which has the characteristics of low energy consumption and good atomization. The feed ratio is petroleum coke: water = 100:8, and is uniformly stirred in a mixer together with cobalt hydroxide, and then added to the furnace, and the furnace temperature is controlled at 1000 to 1100 °C. The cobalt oxide produced by the reverberatory furnace contains about 76% cobalt. According to the required ratio: cobalt oxide: petroleum coke: limestone = 100: (8 ~ 9): (5 ~ 7), the ingredients are put into the electric furnace, and the surface of the material is paved with a small amount of coarse Cobalt residue to facilitate arc smelting. After the charge is melted, the temperature of the furnace is controlled at 1550 to 1650 ° C, and the slag and slag are operated to be heated and cast into an anode plate. Jinchuan's anode plate specifications are 530mm × 230mm × 40mm. The chemical composition of the crude cobalt anode plate is Co>95%, Ni<0.45%, Cu<0.65%, Fe<1%, Pb<0.003%, Zn<0.002%, S<0.6%, C<0.05%.
