An initial capex of $607 million is estimated to build a 20,000 tonnes per day mineral processing plant and owner operated, open pit truck and shovel mine. The flowsheet involves primary crushing followed by semi-autonomous grinding, ball milling, gravity circuit, and flotation.
Read MoreBall mill design requires a Bond work index, BWi, for ball mills at the correct passing size; SAG mill design requires an appropriate SAG test, for example, SPI (Chapter 5). Flotation design needs a valid measure of kinetics for each sample, including the maximum attainable recovery and rate constants for each mineral ( Chapter 12 ).
