Improved leach recovery - IsaMill™ Advantages | Isamill

In simple leaching circuits the purpose of grinding is liberate the particle and expose fine grained minerals to leachant (e.g. exposing fine gold to cyanide). In more complex leach environments such as those treating refractory ore bodies the "refractory" minerals can be passivated by reaction products forming a 2-3 micron "rim" on the particle.
