Fluorspar; containing by weight 97% or less of calcium fluoride

HS code 252921 covers fluorspar, a mineral that is a critical raw material for various industries. Fluorspar, also known as calcium fluoride, is an essential ingredient in the production of aluminum, steel, and hydrofluoric acid, which is used in the manufacturing of refrigerants, pharmaceuticals, and other chemicals. As a result, the fluorspar industry plays a vital role in supporting the broader economy and enabling the production of a wide range of essential products.

Fluorspar is primarily extracted from mines and quarries through conventional mining techniques. The raw material is then crushed, screened, and processed to remove impurities and achieve the desired purity levels. Depending on the end-use application, fluorspar may undergo further beneficiation processes, such as flotation or acid leaching, to enhance its quality and meet industry specifications.

The main inputs required for the fluorspar industry include the raw mineral deposits, mining and processing equipment, energy sources (such as electricity and fuel), and water for various processing steps. Additionally, the industry relies on skilled labor, transportation infrastructure, and regulatory compliance to ensure the safe and efficient production of fluorspar.

The primary output of the fluorspar industry is the processed mineral, which is then consumed by various downstream industries. Fluorspar is a key input for the production of 281121 aluminum, 281512 hydrofluoric acid, and 720260 steel, among other applications. The industry also generates byproducts, such as calcium sulfate, which can be used in the construction and agricultural sectors.
