Review of the hydrometallurgical processing of non-sulfide ...

2014-10-1  The Electrolyte Zinc (EZ) Co. of Australia developed a hydrometallurgical process to treat a silicate zinc ore by controlling factors such as pH, time, and temperature in sulfuric acid leaching. The main advantage of this process is its ability to precipitate high concentrations of colloidal silica using simple, continuous procedures.

2012-5-10  Zinc extraction is performed mainly by hydrometallurgical methods. In the hydrometallurgical process, the ore is first leached by a solvent and then before electro-winning a purification process is used to prepare the solution for eletrolysis. During the leaching process of zinc oxidized ore, soluble zinc sulfate forms which stays in solution.

A Brief Summary of Zinc Oxide Processing Methods

2017-6-19  The zinc oxide product quality range could be 70-90% ZnO, it depends on zinc material feed as other elements and compounds are volatilized with zinc: e.g. lead, cadmium, chlorine, fluorine, sodium and potassium. A simple water washing (with minor addition of Na 2 CO 3) of the zinc oxide produced can separate the zinc and lead

History, Deposits, and Production of Zinc

2020-3-30  Hydrometallurgical Zinc Recovery. In Germany, zinc is extracted in the so-called hydrometallurgical process. This involves dissolving the zinc content of the roasted concentrate in sulphuric acid. Iron, lead, and silver remain. These undissolved components can be sold to other companies where lead and silver are recovered.
