Overview
Sefar process filtration solutions support mining and refining operations by matching filter media to process requirements, improving dewatering, yield and uptime while controlling moisture and emissions.

Solutions for efficient, cost-effective and sustainable filtration
Sefar supplies filter media for demanding solid-liquid and solid-gas separations across mineral processing, designed to reduce total cost of ownership through extended service life and stable process performance.

Optimized filtration for all mineral processes
Our products suit a wide range of mineral streams and operating conditions, enabling continuous operation, improved product clarity and reduced solids loss in downstream processes.

Target Markets & Applications

• Alumina — media adapted to the Bayer Process for smelter grade alumina (SGA) and chemical grade alumina (CGA).
• Base & Precious Metals — iron ore, copper, zinc, nickel, gold and other metals (moisture control, reduced solid loss).
• Fertilizers — filter media for acidic and thermal process conditions (acid clarity, phosphate washing, gypsum moisture reduction).
• Titanium Dioxide — media engineered for pigment production clarity and durability.
• Battery Metals — lithium, nickel, cobalt processing (improved purity, recovery and uptime).
• Non‑Metallic Minerals — cement, coal, kaolin, sand (moisture control, extended life, reliability).
