Zinc processing, the extraction of zinc from its ores and the preparation of zinc metal or chemical compounds for use in various products.. Zinc (Zn) is a metallic element of hexagonal closepacked (hcp) crystal structure and a density of 7.13 grams per cubic centimetre. It has only moderate hardness and can be made ductile and easily worked at temperatures slightly above the ambient.
Zinc. Zinc is often found in nature together with lead in sulfide ores. The metals are separated during refining. As zinc is resistant to corrosion and easy to apply, much of
Froth flotation is considered to be the most widely used method for ore beneficiation. In ore beneficiation, flotation is a process in which valuable minerals are separated from worthless material or other valuable minerals by inducing them to gather in and on the surface of a froth layer.
The general focus of this document will be on metaliferrous ores represented by runofmine material described in category 3 above. An exception to the above discussion of mineral processing arises when the valuable component of the ore is extracted directly by chemical methods.
Extractive metallurgy is a branch of metallurgical engineering wherein process and methods of extraction of metals from their natural mineral deposits are studied. The field is a materials science, covering all aspects of the types of ore, washing, concentration, separation, chemical processes and extraction of pure metal and their alloying to suit various applications, sometimes for direct

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.
