$developments in the processing of refractory & complex gold ores$

Based on today’s picture, likely trends could be: 44
• Continued application of PAL for laterites – especially for large projects and higher grade deposits. • Further development of atmospheric agitated and heap leaching, especially for smaller projects, adjunct and satellite operations, and lower grade deposits. • Increased application of pressure oxidation for sulphide concentrates, especially for large projects. • Commercialization of heap bio-leaching for lower grade sulphide ores and those with impurity issues. 45
