Carbon in Column/Leach/Pulp Systems

  • Processing gold and silver requires clear filtrate
  • Durco Filters pressure leaf filters, tubular backwashing filters, and filter presses are necessary to produce precious metals
  • Use pressure leaf filters for clarification
  • Use filter presses for recovery of precipitated precious metals
  • Use tubular backwashing filters to clean barren solution and prevent leach nozzle plugging

Specialty Mining Applications

Molten Sulfur

Molten-Sulfur-filter

Specially designed Durco Filters pressure leaf filters greatly reduce the maintenance costs in molten sulfur processing. Burner cleaning is reduced from a burdensome and costly task every 2 hours to a once every 3 months maintenance event. Shut-downs are minimized and SO2 gas filters are eliminated.

Fluorocarbon Lined Tubular Filters for Strong Acid Filtration

Long-lasting Endurance for Heavy Industrial Use

The Durco Filters PTF Tubular Filter Series contains fluorocarbon-lined tubular backwashing filters for severe service application requiring high flow rates and supreme resistance to corrosion.  These fluorocarbon-lined tubes also contain reusable, backwashable and non-metallic filter elements to provide a cost-effective system for filtering corrosive liquids. They also eliminate the cost and handling of disposable media, thus avoiding operator contact with hazardous materials.

Nothing Like it In the Industry

Durco Filters is the only tubular filter manufacturer that produces a teflon lined tubular filter.
