PROJECT SCOPE
The purpose of this project is to evaluate ultra fine grinding (-10 micron) of sulphide concentrate prior to gold leaching, using IsaMill™ fine-grinding technology. The reason for using this technology is to eliminate the need for roasting sulphide concentrates and the associated environmental issues.
MIPAC SCOPE
• Commissioning and tuning grinding control loops and strategies
• Review and modification of control strategies as required
• Training process operators
TECHNICAL HIGHLIGHTS
• Successful Isamill power draw control
• Thickener inventory control
• Leaching pH control
• On-the-job operator training
