Ore processing flow The ore needs to be dry, less the 15 moisture. The Air Impact Mill can be hand fed or fed by an optional feed hopperconveyor. As the rock is processed through the Air Impact Mill it discharges into a wetting cyclone attached to the mill. The cyclone slurrys the milled ore and discharges to a closed feed trough.

Electrical current within a rock will choose not to flow through the pore-space if the rock forming minerals are more conductive. This occurs frequently in ore-bearing rocks due to the presence of metal-oxides magnetite, illmenite, specular hematite, metal-sulphides pyrite, pyrrhotite, galena and native metals gold, silver, copper.
