Fluorite is mined with the open-pit method using equipment like excavators, loaders, and dump trucks. Mining involves removing the soil and rock above the deposits (the overburden) to expose the deposits, then blasting with explosives to extract the mineral ore. Once extracted, Fluorite is transported to processing facilities for refinements.
