The preferred method for heap leaching is drip irrigation, but in certain condition and applications and when safety regulation permits, sprinklers are also used.
Heap leaching with sprinklers will work well in areas where the wind effect is minimal and when the desired flow rate is very high.
Sprinkler irrigation in mining applications is mainly used for heap leaching of cooper, gold, uranium and nickel. Sprinklers are ideal for slope irrigation, evaporation, dust control, reforestation and can also be installed to complete the leach cycle or provide a final rinse.
Why Sprinklers?
Sprinklers conserve energy and provide exceptional uniformity and are becoming hugely popular in mining industry. Netafim’s sprinklers provide the flow rate at an extremely high uniformity and relatively low operation pressure. The droplet has an ideal size to avoid compacting the soil and on the other hand not to evaporate.
Where sprinklers system is the preferred method, Netafim is the only company that supplies the whole system with products designed for easy storage and later fast installation and reliable operation.
Netafim solutions for sprinkler irrigation in mining:
Netafim has developed a unique sprinkler that can deliver the highest uniformity rate and excellent percolation through the ores in extreme environmental, climatic and working conditions and as a result increase mineral recovery rate. GyroNet™ Turbo is the ideal sprinkler for heap leaching, final rinsing and slope irrigation. Depending on the design and flow rate it can always be used for an efficient evaporation.
All Netafim’s product are supported by NetSpeX™ a web based system which is a smart design tool for optimizing mining’s sprinkler performance in various installation-patterns and operating conditions, to maximize uniformity
GYRONET™ TURBO
GyroNet Turbo™ delivers highly uniform coverage with high precipitation rates and very gentle droplet size.
Why GyroNet™ Turbo?
GyroNet™ Turbo is the ideal sprinkler for heap leaching
- Higher reliability - The sprinkler is made from high-quality raw material, resistant to chemicals and UV radiation exposure
- Robust Design : The unique and robust design of the sprinkler’s rotor, water channer and a special shape of the bridge provides a very high-water distribution uniformity.
- Varying Flow rates : It is available in 5 different flow rates: 200, 250, 300, 400 and 500 l/h
- Low pressure compatible : Can perform optimally at low pressure.

Why MegaNet™?
- ONE-OF-A-KIND INTEGRAL FILTER: MegaNet’s unique built-in filter protects the sprinkler nozzle from being clogged by debris - reducing repair and maintenance costs.
- DOUBLE-DAMAGE PROTECTION: Unique pop-up mechanism - that opens only during irrigation - prevents insects, spiders and dirt particles disrupting sprinkler performance and shields against handling damage.
- INCREASED percolation:Gentle water jets produce relatively small drops near the ground making it ideal for
- HIGH WATER DISTRIBUTION:Unique symmetrical structure splits water into two equal jets, creating more balanced water distribution.
- Robust - Made of UV-protected materials, durable to all climate conditions.

MEGASTAND™
SPRINKLER STAND FOR INSTALLATION WITH NETAFIM™ FLEXIBLE PIPES.
Combination between GyroNet™ Turbo or others sprinklers (with male thread inlet connector 1/2") and flexible pipes: FlatNet™.
The stand consists of the following parts:
- Base
- Arm
- Riser – several units (1, 2 or 3) can be installed together to achieve the desired sprinkler height
If the stand installed comprises only Netafim™ made parts, Teflon is not needed. The parts will be supplied as individual components to allow ordering a stand with height according to requirement (40, 80 or 120 cm).
The Netafim™ MegaStand™ can be connected to field sprinklers with 2" and 3" FlatNet™ pipes.
BASE: Catalog number per 1 unit: 64520-002480 Unit quantity per box: 20 units.
