Impact crushers are versatile crushing machines that can be used in any stage of the crushing process. However, the features and capabilities of different impact crusher types vary considerably. Impact crushers are traditionally classified to two main types: horizontal shaft impact (HSI) crushers and vertical shaft impact (VSI) crushers.

Processing will include 2-stage crushing (jaw crusher and cone crusher) and 2-stage grinding (semi-autogenous-grinding mill and ball mill), resin-in-leach (“RIL”), elution and electrowinning. The nominal throughput rate is projected to be 7,400 tonnes per day (“t/d”), plus 1.5 additional years at a lower rate from residual stockpile feed, for a total 9.5-year mine life.

When intercooling and reheating are used, regeneration becomes more attractive since a greater potential for regeneration exists. The back work ratio of a gas-turbine improves as a result of intercooling and reheating.
