Not all anthracite is the same. The parameters that matter fixed carbon content, sulphur, phosphorous, volatile matter, particle size distribution vary significantly between sources, and that variation has direct consequences: for furnace productivity in metallurgical operations, and for filter bed performance in water treatment systems.

We at MICBAC INDIA supply two distinct anthracite product families, each sourced and processed for a specific industrial purpose. ANTHRAZITE™ for the metallurgical and industrial fuel market where fixed carbon up to 98%, near-zero phosphorous, and controlled impurity profile define the specification. ANTHRAZORB™ for water treatment filtration where angular grain structure, low density, EN-12909 compliance, and a 10–15 year service life in dual-media filter beds define the specification.

ANTHRAZITE™ is sourced from deep-seam deposits that consistently produce fixed carbon between 89% and 98% — at the high end of what the commercial anthracite market can supply. With sulphur below 1% and phosphorous at just 0.05%, it is the preferred carburizer and recarburizer for steelmakers and foundries where impurity control directly affects melt quality and product yield. Six standard size fractions from 1–3mm to 10–30mm cover the full range from fine carburizer injection to large granule furnace charge.

ANTHRAZORB™ is our purpose-built filter-grade anthracite for dual-media and multi-media water treatment systems. Sourced from deposits with fixed carbon between 85% and 92%, processed through selection, crushing, washing, and precision screening to the effective size gradations that filter systems require. Angular grain structure maximises bed void space. Low density (750–900 kg/m³) ensures it always settles above the sand layer after backwash maintaining the stratified bed structure that gives dual-media filters their performance advantage. EN-12909 compliant. 10–15 year service life in well-maintained systems.
