Ore properties: The metal mineral of this project was mainly pyrite. The non-metallic minerals were quartz, calcite, mica. The raw ore contained 4.70g/t of gold, 4.63g/t of silver, 20.10% of iron and 20.55% of sulfur.
Xinhai Solution: Two stages closed circuit grinding - thickening before leaching - leaching andadsorption - tailings dry stacking
Project Results:Malaysia CNMC 700TPD Gold Project was put into operation in just 6 months. The actual capacity and recovery reached up to 700t/d and 95% respectively, 100t/d and 2 percentage points higher than the original targets. As a result, better economic benefits were achieved.
