Efficiency and Recovery for Gold Plants

Overview

The challenges faced by typical gold plants include declining head grades, challenging ore types, poor process control and instrumentation, and therefore are often deriving low margins. Process IQ can assist in recovery and efficiency of a gold plant by improving the following:

Improved recovery:

  • Optimising Leach Kinetics: CN/DO ratio, pH, agitation/mixing, carbon adsorption – reduced soluble gold losses and residence time
  • Optimising Process Control: control of CN concentration to setpoint, reject disturbances, improve carbon movement, improve detox: reduce WAD CN in tails and improve operation of leach feed & tails thickeners (density, reagent & flocculent control)

Improved efficiency:

  • Reduced carbon attrition
  • Reduced cyanide consumption
  • Reduced DO losses

 

LeachStar Advanced Process Control (APC) improves gold plant efficiency and recovery through robust strategies for:

  • Leach feed control / Thickener stabilisation and optimisation
  • Leaching control: Cyanide concentration, pH, DO
  • Carbon management by optimising carbon transfer
  • Detox control: WAD Cyanide concentration

LeachStar APC not only reduces gold and carbon losses, but also saves the plant up to 20% on reagent consumption.
