MINING ENGINEERING DRAINTUBE FT

When draining leachates as part of metal extraction operations in leach pads, DRAINTUBE^® FT provides a suitable solution for a full and timely collection as well as the disposal of metal-rich solutions. Once contained, DRAINTUBE^® FT is capable of withstanding very high compressive stress, even at high temperatures.

The design of leach pads in heaps meets strict environmental requirements in terms of stability and insulation. DRAINTUBE^® FT is therefore a first-class technical alternative to collect leachates and protect waterproofing barriers. In addition to being low-cost and very easy to implement, it has a better impact on the environment as it replaces granular layers, and reduces or eliminates the transport of these resources.

Connection to the collector via the Quick Connect system

The Quick Connect system directly connects the mini-drains from the DRAINTUBE^® FT to the main collector drain. In the event of gas drainage, it generates negative pressure in the entire system.
