Zinc is a chemical element with symbol Zn and atomic number 30. It is the first element in group 12 of the periodic table.In some respects zinc is chemically similar to magnesium: both elements exhibit only one normal oxidation state (+2), and the Zn 2+ and Mg 2+ ions are of similar size. Zinc is the 24th most abundant element in Earth's crust and has five stable isotopes.
The standard process for zinc sulphide concentrate treatment is the Roast-Leach-Electrowinning (RLE) process. This process is highly efficient in converting the zinc to special high grade zinc metal by roasting to zinc oxide, acid leaching and purification and electrolysis to zinc …
Zinc smelting is the process of converting zinc concentrates (ores that contain zinc) into pure zinc. Zinc smelting has historically been more difficult than the smelting of other metals, e.g. iron, because in contrast, zinc has a low boiling point .
