Influence of grinding on flotation of industrial semi

Nov 01, 2019 The effect of the grinding and liberation changes of sulphide minerals on their floatability in the flotation process of concentrate from rougher flotation from the Rudna Concentration Plant (KGHM Polska Miedz SA) was analyzed. It has been found that the upgrading selectivity decreases with the decreasing size of sulphide particles regardless of liberation degree.

Shifting the Comminution Workload from Secondary to

The idea is to shift the grinding workload from secondary grind stage to regrinding stage by coarsening the SAG-Ball mill-crusher (SABC) circuit product to 300 µm and introducing the coarse flotation in between the secondary and regrind stages plus introducing the energy efficient grinding technology such as the TowerMill to prepare the feed for rougher flotation with particle size of 95 µm.

Abstract. A technique for simulating a continuous flotation circuit from batch test data is described and demonstrated. Because the simulation is based on a kinetic analysis of the batch data, a method for accurately collecting rate data from a batch test is also described; and based on the kinetic results, it is shown that an optimum time can be specified for a flotation stage.
