Slide 16: Metallurgy & Ore Processing
Metallurgy & Ore Processing Gold & Silver Extractions • Gold extraction from the ore types at Tujuh Bukit have been shown to be relatively insensitive to crush size in bottle roll and column leach test-work up to a crush size of 75mm. The selected process option consists of: – Two-stage open circuit
Slide 17: Metallurgy & Ore Processing
Metallurgy & Ore Processing Expected Field Leach Performance Figure below presents expected field leach performance employing a simple open circuit crushing plant (P100 ~75mm). Leach kinetics indicate 50% to 80% extraction of gold from oxide ores in 30 days of field leaching, or over 75% of final ex
