• Fine Grinding as Enabling Technology – The IsaMill

    • the liberation impact – in simple cases the grinding is simply to expose fine grained minerals to leachant (eg exposing fine gold to cyanide). In this case dissolution of the host mineral is not needed. • the sizing impact – "refractory" minerals often do react, but are passivated by reaction products forming a 23 micron "rim" on the particle. For a 30 micron particle this ...
