Applied Mineralogy in Ore Dressing SpringerLink

Mineralogy applied to ore dressing is a reliable guide for designing and operating an efficient concentrator. A procedure for conducting 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.
