Zinc is an important non-ferrous metal raw material. At present, zinc is second only to copper and aluminum in the consumption of non-ferrous metals. Zinc metal has good calendering, wear resistance and corrosion resistance, and can be made into physical and chemical with various metals. An alloy with better performance. The main products produced by […]

Copper powder oxidation method uses copper ash and copper slag as raw materials to be calcined, and is initially oxidized by gas heating to remove moisture and organic impurities in the raw materials. The resulting primary oxide is naturally cooled, pulverized, and subjected to secondary oxidation to obtain a crude copper oxide. The crude copper oxide

1. Copper sulfate method. Reaction equation: 2CuSO+4NaHCO→CuCO·Cu(OH)↓+2NaSO+3CO↑+HO Method of operation: the baking soda is formulated into a solution having a relative density of 1.05, first added to the reactor, and at 50 ° C, the purified copper sulfate solution is added under stirring to control the reaction temperature at 70-80 ° C, and the reaction
