Cyclone Monitoring System Improves Operations at KUC's Copperton Concentrator--New technology allows mill to identify coarse material fouling flotation feed

摘要

The Value of Early DetectionThe target grind size for flotation feed at Copperton is 32% +150 microns (100 mesh). Cyclone product greater than 150 microns is considered coarse Cor oversize). Particles 6 mm (-0.25 inches) or greater can be considered "rocks" and a large flow of this material can block the internals of the flotation cells, significantly impacting their performance. Figure 2 shows an example of the material that has been flushed from a rougher row after a severe rock event. Some causes of "rock" events include: SAG mill grate or trommel panel failure; cyclone failure, and degradation or failure of SAG mill pebble removal system.
