for conductiqg mineralogical studies in conjunction with ore dressing was, therefore, developed. The procedure includes characterizing the ore and analysing the mill products. Characterizing the ore involves identifying the minerals, determining the mineral quantities, and measuring the size distributions of the minerals in the uncrushed ore.
