Zinc ores are widely distributed throughout the world, although more than 40 percent of the world’s output originates in North America and Australia. The common zinc-containing minerals are the zinc sulfide known as zinc blende or sphalerite (ZnS), a ferrous form of zinc blende known as marmatite [(ZnFe)S], and a zinc carbonate known as calamine or smithsonite (ZnCO 3).A complex crystal-chemical investigation based on spectroscopic methods, Electron MicroProbe Analysis (EMPA), and Laser Ablation Inductively Coupled Plasma Mass Spectrometry (LA-ICP-MS) was made on sphalerite samples from the Terézia and Rozália veins in the Banská Štiavnica ore district.

The name was changed in 1823 to orthoklas by Johann Friedrich ...

Natural zinc ores include sphalerite (blende or sphalerite, chemical formula: ZnS), anorthite (hemimorphite or calamine, chemical formula: Zn4Si2O7(OH)2・H2O), smithsonite (chemical formula: ZnCO3), and zincite (chemical formula: ZnO). Zinc ore is basically produced in a state in which it is combined with other elements such as sulfur, ...

The general chemical formula of sphalerite is written (Zn,Fe)S to imply that the ratio of the two metals (Zn and Fe) is variable from one specimen to other, but the ratio of total metal to S remains constant. Zinc is ordinarily present in greater amount than Fe (Krauskopf 1979).
