Is sphalerite a mineral or a rock.

Ores And Minerals - Ores and Minerals ... Sphalerite (zinc blende), a mineral of zinc sulphide, is the most common zinc ore. You now know about ores and minerals. ... Ore is natural rock or sediment that contains one or more valuable minerals, typically metals, that can be mined, treated and sold at a profit.Identifying Pyrite. Hand specimens of pyrite are usually easy to identify. The mineral always has a brass-yellow color, a metallic luster and a high specific gravity. It is harder than other yellow metallic minerals, and its streak is black, usually with a tinge of green. It often occurs in well-formed crystals in the shape of cubes, octahedrons, or pyritohedrons, …In a given chemical class, each mineral contains the same specific element or chemical compound but in combination with different metals. For example, galena (PbS) and sphalerite (ZnS) are both sulfide minerals, but galena contains lead and sphalerite contains zinc. The minerals of Ohio are grouped into ten chemical classes:Because lead is a primary element in galena, the mineral has a high specific gravity (7.4 to 7.6) that is immediately noticed when picking up even small pieces. Galena is soft with a Mohs hardness of 2.5+ and produces a gray to black streak. Crystals are common and they usually are cubes, octahedrons, or modifications.If so, this list will help you with identification . Start by inspecting a yellow or yellowish mineral in good light, picking a fresh surface. Decide the mineral's exact color and shade. Make a note of the mineral's luster and, if you can, determine its hardness, too. Finally, try to figure out the geologic setting that the mineral occurs in ...
