Generally, ore deeper than 150 to 200 feet required more modern pumping methods. Many deposits were shallow and limited in size, and were generally unproductive after 5 to 10 years. The small, independently operated milling and smelting plants would then move to a new location, making it difficult today to locate sites of former operations.
Lead ores are usually associated with other metals, particularly silver which can be mined at the same time and zinc, which can cause problems during smelting. The Sulfide Mineral, Galena, a Lead sulfide, PbS, is the most important ore mineral of Lead. It can contain 86% Lead. Its metallic, Lead-gray cubic crystals (isometric system) and ...
The PSD shows the problem in attempting to produce lead in a single step. The volatility of PbS and PbO make it desirable to keep the gas volume as low as possible (i.e., use pure O 2 in smelting). But this means operating along the pSO 2 =1 isobar, thus producing a large amount of PbO-containing slag in order to produce a low-sulfur bullion. Producing a low-sulfur bullion requires the use air ...
