Anhydrous Copper Acetate ( https://www.wsdty.com/product/copper-acetate/anhydrous-copper-acetate/ ) production process: The vanadium-zinc ore used in this project contains about 516% of V2O. It runs 24 hours during production, 6 hours per batch, 4 batches per day, and the input of 2t vanadium-zinc ore per batch. Day running. The following procedures are calculated according to the raw materials of each batch of 2t vanadium zinc ore. The vanadium-zinc ore is milled by adding water wet method. The milled ore is injected with 98% sulfuric acid in the reaction tank. The injection amount of sulfuric acid accounts for 30% of the ore. Water (can be added by washing and filtering water), sulfuric acid is injected under the water surface mixture through the conduit to form dilute sulfuric acid for leaching, reducing the generation of acid mist, the reaction process is 2h, and the reaction controls the pH at 1.5-2.
After the reaction, the slag is washed with steam condensed water. The washing water volume is 8t. After the washing water is filtered, 1.5t of slag (mainly containing SiO2 and a small amount of V2O5) is produced. It is intended to be sold. After filtering, the precipitated water mainly contains SiO2. In the reaction tank; after the reaction, add about 0.36t of ammonium sulfate for the first precipitation of vanadium. After precipitation, filter to obtain the mother liquor. About 8t, the mother liquor contains 12% Zn. Adjust the pH to 7 by adding ammonium sulfate. After filtration, obtain crude zinc carbonate. About 0.26t; the mother liquor is concentrated and crystallized again to obtain ammonium sulfate, about 11t, this part of ammonium sulfate is sold as a by-product; after the vanadium filtration, the liquid alkali is added for alkali dissolution, and after the filtration, 0.1t of iron slag is generated, and the iron slag is collected Sale; after alkaline solution filtration, add 0.1t sulfuric acid to adjust the pH to neutral to remove impurities, mainly containing impurities such as Si, Zn, etc. about 0.02t, add 5t ammonium sulfate for vanadium precipitation, centrifugal separation after vanadium precipitation to obtain the main product partial vanadium Ammonium acid, about 1.56t.
