HEAP LEACHING WITH DRIP : HIGHER PRODUCTION THROUGH SUPERIOR TECHNOLOGY

Today the use of drip irrigation is accepted as a "best practice" method for heap leach mining worldwide for 90% of the gold, copper and uranium mines and it is also used on nickel and extraction of lithium. Driplines help to achieve higher ore extraction rates in heap leaching by ensuring a very precise and uniform application of the leaching solution, less water loss due to evaporation and a better uniformity of the leach solution’s distribution

Drip irrigation & Valves for Mining

LEACH LINE™ A DRIPLINE

Leach Line™ A is the industry leading non-pressure compensated dripper for heap leaching in mines. The dripper is welded in the wall of the seamless pipe assuring strength and durability. Available diameters: 16 and 20 OD (outside diameter).

 

Why Leach Line™ A?

  • Industry’s widest flow path : Large and wide dripper filtration area allows large particles through short flow path to ensure optimal performance.
  • Superior clogging resistance: TurbuNextTM labyrinth assures wide water passages, large deep and wide cross section improves clog resistance.
  • High uniformity: Injected molded drippers ensure high uniformity and very low CV, that assure uniform irrigation along all the leaching cycle
  • Robust: Internal emitter protected against mechanical damage.

 

Applications

  • On-surface or subsurface installations in heap leached mines
  • Flat terrain or slopes of heap leached pads ANTI-MIGRATION DRIPPERLINE RING (OPTIONAL) Pre-installed ring
  • Prevents solution migration on uneven surfaces and slopes
  • Economical - saves labor
  • Available for 16 and 20 mm OD dripperlines
  • Pre-installed on the dripperline during production (optional)

  • pH range: 1.5 - 14
  • Inside diameter and wall thicknesses: (16mm) 35 mil, 40 mil & 45 mil (18mm) 25 mil, 35 mil & 45 mil (20mm) 45 mil & 48 mil
  • Nominal flow rates (GPH): 0.26, 0.4, 0.5, 0.79, 1.0, 2.0
  • Common spacings: 18”, 24”, 30”, 36”, 42”, 48”, 60” (additional spacings available)
  • Maximum operating pressure: 45 psi
  • Recommended filtration: 80 mesh
  • Available flow rates: 1.0, 1.5, 2.0, 3.0, 4.0 and 8.0 l/h.

Uniram™ RC Ω

UniRam™ RC is a pressure compensated dripper for flexibility of uniform leaching even on sloping terrain – resulting in a uniform  flow of  solution from the top of the pad to the bottom of the slope. An anti-migration mechanism stops water from running down the tube, preventing bottom pooling. It is made with UV and acid resistant polyethylene tubing which is  the highest quality  resins  available. Available diameters: 16, 20 mm OD (outside diameter).

Available flow rates: 1.0, 1.6, 2.3 and 3.5 l/h.

 

Why UniRam™ RC Ω?

  • Uniform flow rates: Pressure compensation over a wide pressure range (up to 4.0 bar) produces uniform dripper flow rates from each dripper outlet.
  • Continuously self-flushing: Flushes debris as it is detected, throughout operation, ensuring uninterrupted dripper operation.
  • Clog resistant : Self-flushing system with wide filtration area improves resistance to clogging thus making UniRam™ highly resistant.
  • Wide flow path: TurboNet™ labyrinth assures wide water passages with large deep and wide cross section to improve clog resistance. Widest water passages within the dripper.
  • Robust: Seamless, one-piece construction prevents damage to drippers during installation and retrieval. Anti-migration technology prevents water runoff along pipe.

 

Applications

  • On-surface or subsurface applications.
  • Slopes.
  • When high uniformity and longer runs are required.
  • For long-term, re-use.

 

Anti-Migration dripperline ring

  • Pre-installed ring
  • Prevents solution migration on uneven surfaces and slopes.
  • Economical – saves labor cost.
  • Pre-installed on the dripperline.

DRIPNET PC™ Ω

HEAP LEACHING FOR GOLD & SILVER MINES

DripNet PC™ is a pressure compensated dripper for flexibility of uniform leaching even on sloping terrains – resulting in a uniform flow of solution from the top of the pad to the bottom of the slope. An anti-migration mechanism stops water from running down the tube, preventing bottom pooling. Made with UV and acid resistant polyethylene tubing; the highest quality resins available. Available diameters: 16, 20 mm OD (outside diameter).

Available flow rates: 1.0, 1.6, 2.0 and 3.0 l/h.

 

Why DRIPNET PC™ Ω?

  • Uniform flow: Pressure compensation over a wide pressure range (up to 3.5 bar) produces uniform dripper flow rates from each dripper outlet.
  • Continuously self-flushing: Flushes debris as it is detected, throughout operation, ensuring uninterrupted dripper operation.
  • Clog resistant : Self-flushing system with wide filtration area improves resistance to clogging thus making DripNet PC™ highly resistant.
