Mining and Ore Processing Mercury Pollution. Estimated Population at Risk: 1.5 Million. Description. Mining and ore processing occurs throughout the world and consists of extracting minerals, metals, and gems from surrounding earth and ore. Industrial mines vary in size, with some being quite small operations and others very large.
The majority of the deposits are mixtures of minerals, hence lead ore is usually obtained as a byproduct of other metal mining such as zinc, silver or copper. In fact, lead ore is a main source of silver and contributes substantially towards the world's total output. The most common lead ore is galena (PbS), which contains 86.6% lead.

Zambia (Kabwe) - Lead Mines - Pure Earth. Ore veins with lead concentrations as high as 20 percent have been mined deep into the earth and a smelting operation was set up to process the ore.
Lead processing, preparation of the ore for use in various products. Lead (Pb) is one of the oldest metals known, being one of seven metals used in the ancient world (the others are gold, silver, copper, iron, tin, and mercury). Its low melting point of 327 °C (621 °F), coupled with its easy
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 multi-step process. First the lead ore is ground into small particles that are less than 0.1mm, giving the ore a texture similar to table salt.
For example, in 2010, more than 400 children died in Zamfara, Nigeria from acute lead poisoning caused by unsafe mining and processing lead-containing gold ore. People grinding the ore, often in and around their homes, contaminated at least 180 villages over a wide area.
