Zinc can be refined by the process of electrolytic refining. In this process, impure zinc is made the anode while a pure copper strip is made the cathode. The electrolyte used is an acidified solution of zinc sulphate (ZnSO4). Electrolysis results in the transfer of zinc in pure from the anode to the cathode.

Jul 28, 2017· Copper is considered as one of the oldest metals known to man, and is distributed in the form of around 400 copper alloys. Even in the human diet, Copper is a nutrient essential for good health. To source it, humans can consume copper-rich foods such as organ meats, shellfish, almonds, broccoli, and dried beans, to name a few.
The different steps in extraction of copper are: Crushing and Concentration: The ore obtained from mines are broken down into small piece by jaw crusher and then pulverized. The ore being sulphide ore is concentrated by froth floatation process.
Manganese (Mn) and calcium (Ca) are both metal cofactors required for photosynthetic oxygen evolution (1). The functional roles for these ions in the O2-evolving reactions are not completely known. They are studied by comparative spectroscopic measurements between intact and metal-depleted samples.
