Sphalerite mineral.

Resinous minerals have a luster similar to violin resin or pine pitch. The most common mineral example is a resinous variety of sphalerite (ZnS) such as that shown in the photo below (Figure 3.26). Sphalerite, however, has other appearances. In fact, the name sphalerite is from the Greek sphaleros which means deceiving or …Sphalerite is a zinc ore, and its name pertains to the Greek word that means ‘treacherous’. This is because it looks a lot like Galena, only it does not contain lead, much to the disappointment of early miners. Sphalerite is a significant zinc ore which is usually found in hydrothermal veins. It can also be found in limestones where ore ...Sphalerite is a zinc sulfide mineral with a chemical composition of (Zn,Fe)S. It is found in metamorphic , igneous , and sedimentary rocks in many parts of the world. Sphalerite is the most commonly encountered zinc mineral and the world's most important ore of zinc .

The principal ore minerals are galena and sphalerite with accessory magnetite, chalcopyrite and pyrite, whereas the gangue minerals contain garnet, diopside, epidote, quartz and calcite, with minor tremolite, actinolite, chlorite, sericite and albite, etc. (Figs. 4, 5).

Sphalerite is one of the few minerals that can range from gemmy transparent crystals to dark, metallic -black crystals. An interesting variety of Sphalerite is known as Schalenblende. Schalenblende is banded variety associated with Wurtzite and often also Pyrite and Galena that forms strange concentric shapes.In leaching process of sphalerite containing a lower concentration of iron, the decrease in zinc dissolution rate (as compared to a greater iron-containing sphalerite mineral) was attributed to formation and growth of a polysulfide surface layer during the initial rapid leach period (Weisener et al., 2004).The other mineral that can carry significant indium in base metal ores is chalcopyrite (e.g., Gaspar, 2002). Concentrations of indium are, however, lower than in co-existing sphalerite (e.g., Cook et al., 2011) where the two minerals co-exist, suggesting a strong fractionation into the zinc sulphide. Chalcopyrite can potentially account for a ...
