Zinc blende, also known as sphalerite, is a mineral composed primarily of zinc sulfide (ZnS). It is the main ore of zinc and is typically found in sedimentary rocks. The mineral has a distinctive crystal structure, often forming in a cubic shape, and can appear in various colors, including yellow, brown, and black. This mineral is important in the mining industry as it is the primary source of zinc, which is used in galvanizing steel, making alloys, and producing batteries. Zinc blende is often associated with other minerals, such as galena and pyrite, in ore deposits.
