Uses of Zinc | Supply, Demand, Production, Resources
Zinc is commonly found in mineral deposits along with other base metals, such as copper and lead. Zinc deposits are broadly classified on the basis of how they are formed. Zinc is produced mainly from three types of deposits: sedimentary exhalative (Sedex), Mississippi Valley type (MVT), and volcanogenic massive sulfide (VMS).

Zinc Sulfide - an overview | ScienceDirect Topics
Lead concentrates are usually accompanied by zinc in the form of zinc sulfide. During roasting, the zinc sulfide turns into zinc oxide. Especially in the shaft furnace process for lead production, the reduction rate is set in such a way that lead is reduced while zinc stays as oxide and mainly ends up in the slag.
Zinc sulfide - Wikipedia
Lead and Zinc Lead and zinc ores are usually found together with gold and silver. A lead-zinc ore may also contain lead sulfide, zinc sulfide, iron sulfide, iron carbonate, and quartz. When zinc and lead sulfides are present in profitable amounts they are regarded as ore minerals. The remaining rock and minerals are called gangue.
Zinc Sulfides - an overview | ScienceDirect Topics
Galena, a lead sulfide (PbS), is heavy, brittle, and breaks into cubes. Sphalerite is a zinc sulfide (ZnS) mineral that is brownish, yellowish, or black. It ordinarily occurs with galena and is a major ore of zinc. The iron sulfide pyrite (FeS), which is also called fool's gold, is common in nearly all types of rocks.
Zinc Sulfide - Assignment Point
Applications of Zinc Sulfide. Zinc sulfide is actually used as an infrared optical material, transmitting from visible wavelengths to just over 12 micrometers. It can be used planar as an optical window or shaped into a lens. It is made as microcrystalline sheets by the synthesis from hydrogen sulfide gas and zinc …
Missouri Lead Mining History by County - DNR
Lead-Zinc in Southwest Missouri outside the Tri-State District Lead was first mined in Greene, Webster, and Christian counties in the 1850s. Most mining in southwest Missouri from the 1870s to the 1940s was in these three counties plus Taney, Ozark, Wright, Dade, Howell and Texas counties.
