Lead/Zinc Ore. Lead and zinc often occur in the same ore. Copper is also present in some ores. Froth flotation is again employed to produce marketable concentrates of both. The process is identical in principle to the flotation of other minerals. The figure on the right is .
Usually, lead is found in conjunction with other metals such as silver and zinc. Lead materials are mined as a by product of these other more valuable metals. Extracting the lead materials from the ore is a multistep process. First the lead ore is ground into small particles that are less than, giving the ore a texture similar to table salt.
Also, the recovery of silver minerals occurring in a lead, zinc sulfide ore is efficiently accomplished using Flowsheet #2. The process consists of selective flotation to produce a mixed silver, lead concentrate for maximum smelter return and a separate zinc concentrate.

History of Lead Mining in Missouri . It is no coincidence that Missouri''s official State Mineral is Galena, the major source of lead ore. For most of the late 19th and early 20th Centuries, Missouri was the global leader in lead production, and even today some of the largest and most important remaining lead deposits in the world are located in southeast Missouri.

In mining, the ore is extracted by drilling or blasting and then crushed and ground. The ore is then treated using extractive metallurgy. The Froth flotation process separates the Lead and other minerals from the waste rock (tailings) to form a concentrate.
Ancient smelting was done using loads of lead ore and charcoal in outdoor hearths and furnaces. Although lead is a common metal, its discovery had relatively little impact in the ancient world. It is too soft to be used for weapons (except possibly as sling projectiles) or for structural elements.
