Chat (mining)

Chat is fragments of siliceous rock, limestone, and dolomite waste rejected in the lead-zinc milling operations that accompanied lead-zinc mining in the first half of the 20th century. Historic lead and zinc mining in the Midwestern United States was centered in two major areas: the tri-state area covering more than 2,500 square miles (6,500 km 2) in southwestern Missouri, southeastern Kansas

Lead Lead Alloys

This includes lead concentrate and refined market lead (99.97% and 99.99%), as well as lead-antimony alloys, copperised-lead alloys, calcium lead alloys and calcium tin-lead alloys. Lead concentrate is essentially a mineral called galena, which predominantly contains lead and sulphur. Smelting converts this into a metallic lead form.

Ore Crushing and Grinding

Ore crushing and screening, grinding and classification are essential preparatory work before separation to get proper ore size. There is a balance to keep proper ore size neither too rough (insufficient liberalization) and too fine (over-crushed) in order to achieve high recovery rate and high efficiency.

Collection and recycling of used lead

Lead wastes are dangerous for the environment, so must be recycled responsibly. Recyclable to infinity, lead is the most recycled metal in the world with one of the best mastered recycling processes. More than 60% of global production comes from recycling and this rate is growing every year.

Environmental Risks of Mining

Environmental hazards are present during every step of the open-pit mining process. Hardrock mining exposes rock that has lain unexposed for geological eras. When crushed, these rocks expose radioactive elements, asbestos-like minerals, and metallic dust. During separation, residual rock slurries, which are mixtures of pulverized rock and
