Slide 25: Process Selection and Testing
Process Selection and Testing • A pre-requisite is representative samples of all expected ore types. • Petrographic, analytical and crush tests and various process tests are required to characterise the ore. • Testwork must yield probable operating conditions, processing costs and information for eq
Slide 26: Process Selection and Testing
Process Selection and Testing • From a knowledge of the above it is possible to eliminate inapplicable techniques from laboratory investigations. Between 10% – 15% CaCO3 either acid or alkali could be applicable however >15% CaCO3 only carbonate leaching will be viable; Sulphide minerals react w
