New tools for the mineral processing test engineer

Many new evaluation tools have been developed since the early 1990’s to aid the minerals processing test engineer. The areas of comminution, gravity concentration, flotation, and process mineralogy have received particular attention. This paper will describe new laboratory procedures in the areas of SAG mill testing, gravity concentration, and flotation testing. Computer assisted mineralogical examination equipment, new generations of mass balancing programs, and simulation programs will also be discussed.
