Zinc ore occurs in two types of deposit: as primary zinc ore in thin veins known as rakes, or a secondary deposit formed by weathering of the primary mineral veins. Zinc ore is most commonly found as zinc carbonate (ZnCO3), known as calamine or smithsonite. It generally occurs as .

Galena Group. Galena is the primary ore mineral of lead. Worked for its lead content as early as 3000 BC, it is found in ore veins with sphalerite, pyrite, chalcopyrite, tennantitetetrahedrite, etc. and in skarns, as well as in sedimentary rocks where it may replace carbonate beds or be deposited in pore spaces.

Because its position in the reactivity series of metals, zinc can be 'just' extracted using carbon (coke) in a high temperature smelting furnace. – it is a sort of displacement reaction. Zinc is extracted from either zinc blende/sphalerite ore (zinc sulphide) or sometimes calamine/Smithsonite ore (zinc carbonate).
Gold recovery from copper– zinc ores is usually higher than that obtained from either a lead–zinc or copper–lead–zinc ore. This is attributed to two main factors. When selecting a reagent scheme for treatment of copper–zinc ores, there are more choices than for the other ore types, which can lead to the selection of a reagent scheme which is more favourable for gold flotation.

Then the lead ore is separated from the zinc ore. A chemical called a depressant is added which is soluble in water (for example, zinc sulfate) and the zinc ore sinks and the lead ore is skimmed off. Later, a chemical such as copper(II) sulfate is added and the zinc ore now floats and is skimmed off.

Sphalerite (zinc sulfide) is the primary ore mineral from which most of the world's zinc is produced, but a number of other minerals that do not contain sulfide contain zinc as a major component. Much of the early zinc production was from nonsulfide deposits; however, as these resources were exhausted, production shifted to sulfide deposits.
