Bonded Alumina Ceramic Disc Filter Plates for dewatering in Mining

Alumina Ceramic Membrane Filter Plates for Mining Applications

Why the Mining Industry Depends on Ceramic Filter
Plates made by Refractron

Exploiting the effects of capillary action to reduce energy consumption, ceramic disc filters achieve the lowest OPEX costs to dewater any mineral concentrate or tailings slurry when the feed is suitable.

Refractron plates have a history of performance in the filtration of both concentrate and tailings applications including chromite, coal, copper, gold, ilmenite, iron (magnetite and hematite), lead, nickel, pyrite and zinc.

Why Choose Refractron Membrane Ceramic Filter Plates?

  • 30+ years of technological innovation making ceramic membrane filter plates for OEMs and mining companies.
  • Higher capacity with sustained performance. Improved cleanability and resistance to clogging.
  • Achieve transportable moisture limits for concentrates, allow for the possibility of dry stacking tailings, and avoid costly secondary drying operations.
  • Robust construction counters exposure to acid and enhanced membrane hardness resists pitting from ultrasonic cleaning used to regenerate the plates.
  •  Membrane filter plates produce crystal clear, low solids filtrate.
  • Standard sizes available for “drop in” replacement on existing fitlers.  We can also accommodate customized designs.
  • Strict quality conformance maintained with flow testing, strength proof testing, plate alignment and air tightness. Air tightness or bubble point testing ensures wet plates are airtight under vacuum.
  • 100% traceability with serialized markings on every plate.
  • Responsive, USA based manufacturing, sales, service, and technical support.
  • ISO 9001:2015 certified.
