Origin & supply chain +
Sourced from Kandahar, Afghanistan
Bare Syndicate operates a significant fluorspar mining concession spanning 62 km² in Afghanistan's Kandahar province. This strategically located deposit, with estimated reserves of up to 8.8 million metric tonnes, produces fluorspar across all commercial grades — from metallurgical-grade metspar to high-purity acidspar at 97%+ CaF₂. The geological profile features vein-type fluorite mineralization hosted in sedimentary and metamorphic formations, producing exceptionally clean material with low phosphorus and arsenic levels — a key quality differentiator for acid-grade buyers. Our on-site processing includes multi-stage crushing, screening, heavy media separation, and flotation to meet exacting buyer specifications for particle size, purity, and moisture content. The operation benefits from proximity to regional trade routes through Chaman and Spin Boldak border crossings, enabling efficient export via Pakistani port facilities at Karachi and Port Qasim to major fluorspar markets in China, India, Japan, South Korea, and Europe.
FAQ +
What is fluorspar used for?
Fluorspar (calcium fluoride, CaF₂) is used as a flux in steel manufacturing to lower the melting point of raw materials. Acid-grade fluorspar is the primary source for hydrofluoric acid production, while ceramic grades are used in glass, enamel, and ceramic manufacturing.
What is the difference between metspar and acidspar?
Metallurgical grade fluorspar (metspar) has 70–85% CaF₂ and is used as a steel flux. Acid grade (acidspar) has 97%+ CaF₂ purity and is used for producing hydrofluoric acid and fluorochemicals — it commands a premium price due to its high purity requirements.
Where does Bare Syndicate source fluorspar?
We source fluorspar from Afghanistan's Kandahar province, where we operate a 62 km² mining lease with estimated deposits of up to 8.8 million metric tonnes. The deposit yields high-quality fluorspar suitable for metallurgical, ceramic, acid, and cement grades.
What industries use fluorspar?
Fluorspar is used across steel manufacturing (as flux), chemical industry (hydrofluoric acid), glass and ceramic production, cement manufacturing, aluminum smelting, and the production of refrigerants and fluoropolymers like Teflon.
Why is fluorspar considered a critical mineral?
The European Union, United States, and several other countries classify fluorspar as a critical raw material due to its irreplaceable role in fluorochemical production, limited global supply sources (dominated by China, Mexico, and Mongolia), and strategic importance in manufacturing high-tech products including semiconductors, lithium-ion batteries, and solar panels.
What are the environmental considerations in fluorspar mining?
Bare Syndicate employs responsible mining practices including progressive land rehabilitation, water recycling in flotation circuits, dust suppression systems, and waste rock management. Our Kandahar operation adheres to international environmental guidelines for mineral extraction in arid environments.
