Clear fluorite is among the rarest of the many fluorite varieties and was once used in the manufacture of optical lenses. Modern fluorite lenses, though, are usually from commercially manufactured fluorite, rather than natural clear crystals. ^ Top. In Our Future: The Environmental Implications of Fluorite Use

Fluorite. Fluorite [CaF2] is a common accessory mineral in many hydrothermal ore deposits, and its dissolution can release F. The dissolution of some layered silicates, such as biotite, can also release F. Fluorite is the least soluble F-containing mineral that might be expected to form and limit F concentrations in low temperature systems.

There are four main mining methods: underground, open surface (pit), placer, and in-situ mining. Underground mines are more expensive and are often used to reach deeper deposits. Surface mines are typically used for more shallow and less valuable deposits. Placer mining is used to sift out valuable metals from sediments in river channels, beach sands, or other environments.

Apocalyptic Facts About How Mining Affects the Environment .

Mining refers to the process of extracting metals and minerals from the earth. Gold, silver, diamond, iron, coal, and uranium are just a few of the vast array of metals and minerals that are obtained by this process. Mining activities require the clearing of large areas of land. The chemicals used in the mining process often escape into the environment causing large-scale pollution.
