But fluorite from the mines in Illinois took a different path. When the mines closed in 1995, there was no increase in prices, because there was so much material stockpiled in the "pipeline", which runs from the mine to the wholesaler to the dealer, that prices stayed about the same for years.
consumption and trade, namely, the acid grade containing more than 97% CaF 2 and the subacid grade analysing 97% or less CaF 2. The subacid grade includes metallurgical and ceramic grades and is commonly known as metallurgical grade. Fluorite production in the country is scarce. At the global level, the country has less production.

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 Fcontaining mineral that might be expected to form and limit F concentrations in low temperature systems.
Fluorspar, the name used for fluorite when it is sold as a bulk material or in processed form, is sold in three different grades (acid, ceramic, and metallurgical). Acid Grade Fluorspar.
