The Challenge

The Most Abrasive Slurries,
on the Largest Plates.


Mineral processing dewaters the most abrasive slurries on the largest plates in the industry. DFR Technical Textiles weaves heavy-duty monofilament and multifilament cloths in jointless widths up to 3 m for membrane and recessed-chamber presses, for iron ore, base-metal and gold concentrates, tailings dry stacking, coal washeries and kaolin, with reinforced necks and fixings for fast changes.

Built for Abrasive Slurries

Jointless up to 3 m Width

Lower Cake Moisture

Fewer Cloth Changes

Three Problems
We Are Asked to Fix.


Problem

Abrasive slurry, large plates


How our cloth helps

Heavy monofilament and multifilament weaves in high-tenacity yarn take the abrasion; jointless widths up to 3 m cover the biggest membrane plates without seams.

Problem

Wet cake, long cycles


How our cloth helps

Permeability is selected for your particle size, and the smooth face releases the cake cleanly: lower moisture, faster cycles, more tonnes per shift.

Problem

Downtime at cloth changes


How our cloth helps

Reinforced necks, edges and fixing zones extend life between changes; cloths come pre-fitted with velcro, eyelets or pins, so a change is quick.

Flagship Application

Iron Ore
Filtration Solutions.


Iron ore processing demands reliable filtration at every stage. DFR filter press cloths ensure maximum dryness, higher throughput, improved water recovery and consistent performance, even in the most abrasive conditions.

Where DFR Adds Value in Iron Ore

Crushing & Grinding

Ore is crushed and ground to the required size for beneficiation.

Beneficiation

Flotation or magnetic separation of valuable iron minerals to produce concentrate slurry.

Concentrate Thickening

Slurry is thickened to increase solids content and reduce volume.

Filter Press Dewatering

DFR filter press cloths efficiently remove water, producing low moisture filter cake.

Dry Iron Ore Concentrate

Low moisture concentrate enables efficient handling, transport and improved product value.

Three Iron Ore Duties

Concentrate Filtration

For high value iron ore concentrates

  • Lowest possible cake moisture
  • High throughput and consistent cycles
  • Excellent cake release
  • Superior abrasion resistance
  • Longer cloth life and reduced downtime

Tailings Dewatering

For efficient tailings management

  • Maximum water recovery
  • Reduced tailings volume
  • Stable filtration and easy cake discharge
  • Lower disposal and handling costs
  • Environmentally sustainable operation
