摘要: ► Cu is efficiently leached from copper-zinc waste by H2SO4 solutions with Fe3+ ions. ► Fe3+ ions inhibit zinc and iron leaching from converter slag flotation tailings. ► Copper and zinc leaching is controlled by chemical reaction on the particle surface....
Kinetic Modeling and Parameter Estimation for Competing Reactions in Copper Removal Process from Zinc Sulfate Solution In zinc hydrometallurgy, an advanced copper removal process purifies zinc sulfate solution through a series of chemical reactions with recycled underflow b...

Potassium permanganate (KMnO4, 99.5 %), potassium citrate (C6H5K3O7, 99 %), Hydrochloric acid (HCl, 36–38 %), Copper(II) sulfate pentahydrate (CuSO4·5H2O, 98 %), and Copper(II) sulfate pentahydrate (CuSO4·5H2O, 99 %) are purchased from Sinopharm Chemical Reagent Co., Ltd. Synth...
3), in a manner similar to Ybt binding of iron50 and copper51, and zinc binding by the Pseudomonas sp.-derived compound micacocidin A52. Finally, we found that increasing the pH of the solution via addition of 0–5 molar equivalents of NaOD had little effect on the NMR spectrum of ...
The nanoparticle synthesis reaction was based on the co-precipitation method. Iron sulfate (FeSO4·7H2O) and ferric chloride (FeCl3·6H2O) salts were used to synthesize iron nanoparticles, while zinc acetate (ZnC4H6O4·2H2O) was used as starting material for zinc nanoparticles. A fraction of...
reaction, concentration is about 38°Bé. The reaction is filtered, it 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 ...
It is a bright, green shade of yellow made by the precipitation of hydrated zinc potassium chromate from the reaction of so- dium bichromate with zinc oxide and potassium chloride. The lithopone version is merely a co-precipitate of zinc chromate onto barium sulfate to give an extended pigment...
An integrated hydrometallurgical process was used for the zinc leaching and purification from a zinc ore containing 9.75 wt% zinc. The zinc minerals in the ore were hemimorphite, willemite, and calcophanite. Main gangue minerals were quartz, goethite, he
After scrubbing of chloride ions from the organic phase (metal ions are transferred from the solvate into the chelate) and stripping of metal ions from the organic phase with sulfuric acid, the concentrated copper sulfate solution is obtained. The solution does not contain iron ions. The recovery...
