OMC’s scope of work consisted of a pilot plant circuit survey, ore characterisation and interpretation of historical results. From this data the design ore characteristics had to be selected and the optimal circuit configuration determined. The major comminution equipment was then sized.
The flowsheet consists of ROM blending, AG milling, recycle crushing, classification, X-ray fluorescence separation, DMS and sorting. HPGR’s were evaluated for the recycle crushing option for the commercial plant design. OMC’s focus was on the AG milling and recycle crushing sections of the plant design.
