Calamine mineral
Calamine is a historic name for an ore of zinc.The name calamine was derived from lapis calaminaris, a Latin corruption of Greek cadmia καδμία, the old name for zinc ores in general.The name of the Belgian town of Kelmis, La Calamine in French, which was home to a zinc mine, comes from this.In the 18th and 19th centuries large ore mines could be found near the German village of
Zinc ore and mines Minerals and mines Foundations of
Zinc ore ismonly found as zinc carbonate ZnCO 3, known as calamine or smithsonite. It generally occurs as rounded, crystalline crusts or granular,bed masses that have a vitreous or pearly luster and are typically dirty brown or grey in colour.

Zinc is a bh white, lustrous,ic metal, thoughmon commercial grades of the metal have a dull finish. It is somewhat less dense than iron and has a hexagonal crystal structure, with a distorted form of hexagonal close packing, in which each atom has six nearest neighbors at 265.9 pm in its own plane and six others at a greater distance of 290.6 pm. The metal is hard and brittle at most temperatures butes malleable between 100 and 150 °C. Above 210 °C, the metales brittl

Zinc Simple English , the free encyclopedia
Zinc is a reactive metal. It is about as reactive as aluminium and more reactive than most of themon metals, such as iron, copper, nickel, and chrome. It is less reactive than magnesium. Zinc can react with acids, bases, and nonmetals.
Extraction of Zinc Application Of Zinc Refining Process
Themonly available ore used in the extraction of Zinc is called Zinc Blende also known as Zinc Sulphide ZnS. Historically extraction of zinc has been more difficult than extraction of other metals because at temperatures where metals such as iron typically begins to melt, zinc is a gas.
