Overview

Linkan Engineering was selected by Barrick Goldstrike Mines to commission and operate a 4,000 gpm water treatment plant processing complex mine tailings decant. The facility produces clean water for reuse and concentrates leaching reagents for reuse in the milling process.


Linkan provides the membrane expertise requried to operate this high flow facility on a complex mine water source. Feed water conductivities rival sea water but with supersaturations of potential scaling constituents. Linkan provides both computer-based training and hands-on training of all operators. We provide 24/7/365 staffing of treatmetn operators to support the day-today oepratin of the plant.

In our role as technology expert, Linkan provides continual evaluation of treatment efficencies, membrane management, clean-in-place management of fouled and scalled membranes, and advises on opportunities for process improvement. Linkan is presently engaged to engineer improvements to system operations and capacity to the plant originally designed by others. Linkan has provided detailed pilot testing and engineering evaluations to.
