Stage 3: hashing. The hashing stage (corresponding to metal extraction and recovery stages) is a little more complex for gold ores, as the optimal process flowsheet selection choice is heavily dependent on a good understanding of two fundamental geometallurgical parameters, the gold mineralogical associations, and the gold particle …

In Grinding, selecting (calculate) the correct or optimum ball size that allows for the best and optimum/ideal or target grind size to be achieved by your ball mill is an important thing for a Mineral Processing Engineer AKA Metallurgist to do. Often, the ball used in ball mills is oversize "just in case". Well, this safety factor can cost you much in …

In the current study are examined ball mills used in some of the mineral processing facilities in Bulgaria. More specifically MCB 4.5x6 ball mill (МШЦ 4.5х6) working with copper-sulphide ore. SAG 8.5x5.3 mill that is processing gold ore with significant ball load are also examined. Both types of examined tumbling mills
