Product Specification
High Purity Acid Grade Fluorspar CaF₂ 99%
99% fluorspar lump is top-tier ultra-high purity fluorite raw material exclusively processed for high-end fluorochemical, electronic chemical and semiconductor industries. Sourced from our independent high-grade fluorspar mines in Mongolia, the ore undergoes closed-circuit ultra-fine grinding plus eight-stage deep flotation to fully separate fluorite from quartz, calcite and other gangue minerals. The finished lump maintains stable CaF₂ ≥99% with extremely restricted impurity content. Strict batch testing ensures consistent indicators, perfectly matching the strict raw material standards of electronic-grade hydrofluoric acid, lithium fluoride and high-purity fluorite. We maintain sufficient stock at Tianjin Port and welcome long-term annual supply contracts.

Core Advantages
Premium Mine Source Control
Self-operated high-grade fluorspar mines in Mongolia. Strict manual sorting removes all low-grade mixed ore, large quartz and calcite waste stones at the mining stage to minimize initial impurity input.
8-Stage Deep Flotation Purification (Core Superiority)
Adopt ultra-fine closed-circuit grinding to achieve complete monomer dissociation of fluorite and gangue minerals. Eight-time selective flotation removes trace silica and carbonate impurities thoroughly, far exceeding regular 97% acid grade standards to meet electronic chemical production requirements.
Precision Closed-Circuit Crushing & Screening
Two-stage crushing with multi-layer vibrating screen classification, uniform lump size, ultra-low fine powder content, reducing furnace dust and raw material loss during production.
Full Strict Batch Quality Control
Each batch is inspected by full-element lab testing, official COA provided upon shipment. Ultra-low impurities avoid pipeline blockage, excessive sulfuric acid consumption and product contamination in precision chemical production lines, greatly lowering customer production failure rate.
Stable & Customized Supply
Permanent bulk inventory at Tianjin Port. Support small trial orders, large bulk vessel shipments and 12-month long-term supply contracts. Custom packaging, inspection standards and particle sizes are acceptable.
