Missouri Lead Mining History by County DNRHow Ore Sorting Leads to Mineral Processing Success
Early mining in the entire southeast Missouri area was of oxidized ores primarily the lead carbonate mineral cerussite Mining moved onto galena when the more easily smelted cerussite was depleted Numerous small mines produced as much as 1 500 pounds a day of oreMany mineral processing operations are taking a hard look at ore sorting to improve their bottom line Even the slightest sorting inefficiencies can lead to huge financial loss not to mention easily preventable downstream and environmental impacts

Geology What is a Mineral Deposit — Mining FocusMissouri Lead Mining History by County DNR
An ore deposit is a mineral deposit which has high enough grades of metal that makes it economic to mine Essentially this means that per tonne of rock containing the desired minerals the costs of removing the minerals from the rock and separating the metal from the minerals are lower than the value of metal per tonne of rock Rock worth Early mining in the entire southeast Missouri area was of oxidized ores primarily the lead carbonate mineral cerussite Mining moved onto galena when the more easily smelted cerussite was depleted Numerous small mines produced as much as 1 500 pounds a day of ore

Galena The mineral galena information and picturesCommon Basic Formulas for Mineral Processing Calculations
Galena is by far the greatest ore of lead The extraction process to remove the lead from the sulfur is very simple thus lead has been extracted from Galena since the earliest tim Galena from certain regions is rich in silver and some specimens may contain as much as 20 percent silver Because of this silver rich Galena is also an ore of silver Another use of Galena was its importance In concentrating an ore containing these minerals it is usually desirable to recover the lead and the copper in one concentrate the perfect grade of which would be 100 galena plus chalcopyrite If “L” is the lead assay of the crude ore and “C” the copper assay it is easily shown that the ratio of concentration of perfect
