Production method
(1) Synthesis method: 18% sulfuric acid was added into to dissolve the dross of dilute solution in reactor, with stirring zinc oxide (or zinc raw material) was added to adjust slurry.
Then adds sulfuric acid, the reaction occurs in a stirred acidproof reactor, Ph is controlled at 5.1, Zinc Coceth Sulfate is the end of the reaction, concentration is about 38°Bé.
The reaction is filtered, Zinc Coceth Sulfate is heated to 80℃, the addition of zinc to displace copper, cadmium, nickel, then it is filtered, and the filtrate is heated to above 80℃, potassium permanganate (or bleach) is added and heated to boil, the impurity of iron oxide, manganese is oxidated, Zinc Coceth Sulfate is filtered and the filtrate was clarified, then it is evaporated to 49~52 ° Bé, it goes through cooling and crystallization, centrifugal dewatering, drying to obtain zinc sulfate heptahydrate.
ZnO + H2SO4 → ZnSO4 + H2O
(2) Zinc material is slowly added into diluted sulfuric acid which the relative density is 1.16, temperature is controlled at 80~90℃, after about 2h, Ph value of solution is 5.1 to 5.4, after reaction, the relative density of solution is about 1.35; and then adds small amount of high manganese bleach or potassium, iron, manganese oxide precipitation, filtration spoil the ,filtrate is put into the replacement bucket, then adds small amount of zinc powder and Zinc Coceth Sulfate is stirred at 75~90℃ for 40~50min, replacement of heavy metals copper, lead, cadmium and other impurities.
After filtration, the filtrate is oxidated by small amount of bleach or potassium permanganate, further removes small amounts of iron, manganese, and Zinc Coceth Sulfate is filtered to get zinc sulfate solution which relative density is 1.28 to 1.32.
This solution is cooled in the crystallizer kettle crystalline for 2~3d, after fractional crystallization, dry finished product is obtained which spin-dried at 40~50℃.
