ABSTRACT:
A mill for comminution and separation of lump ore and subsequent recovery of relatively dense components of the ore, said mill including a stationary housing defining an ore reduction chamber therewithin, an impactor rotor drum rotatably mounted within said housing, said rotor drum supporting a plurality of circumferentially spaced ore breaker hammers and fixedly supporting a plurality of vanes for directing a high velocity air stream around said ore reduction chamber and defining a central feed region therewithin for receiving said lump ore, a plurality of transverse ore breaker plates fixedly supported within said housing and radially spaced from said rotor drum, an autogenous region in downstream communication with said ore reduction chamber, said autogenous region including a high velocity venturi region, a low velocity expansion region downstream of said venturi region and at least one collector plate arranged such that in use a particle laden air stream is directed through said venturi region and out into said expansion region where further particle comminution occurs and relatively dense particles precipitate and are retained on said collector plate.
