Zinc Industries, in addition to the zinc ingot, produces wastes such as leech cake, cobalt cake, nickel cake.
In the production of metal on the cobalt metal residue which is problematic in electrolysis, it produces a waxy cake that contains a small amount of cobalt, 10 to 18 percent zinc, 1 to 5 percent cobalt, 10 to 20 percent manganese (Mn ) And has a moisture content of between 30 and 50 percent.
Cobalt cake is said to be washed on it during the cake washing process and is below 2%, in which case its cobalt concentrates and reaches about 1.2%.
Cobalt is a strategic and expensive metal that can not be produced in our country at this time. This metal is low in the Earth’s crust. The colors of this metal are used in the dyeing and glazing tile industries and are used to create a pale blue color in the glaze. Metal is also used in some alloys, but it is mostly used in Hi-tech Industries.
