Mining Application
Leachate Isolation
Maximize uptime in your leaching operations with enduring isolation valve technology designed to excel in corrosive media.
Ensure Environmental Protection With Corrosive Media Isolation
In the solvent extraction (SX) process, there is a continuous flow of leachate from leach pads to the SX plant. Isolation valves are installed on these lines to isolate the leaching solution, raffinate, and/or pregnant solution for maintenance purposes. Valves must resist the corrosive media and perform on demand with zero leakage isolation to secure the safety of personnel and the environment.
