We have pgm ore grinding parameters feed size and output size,Apr 01, 2017 · A high chromite content in the concentrate impacts negatively on the smelting efficiency. For this reason, the chromite level in the final concentrate has to be kept as low as possible. PGMs in the UG2 are known to be tiny inclusions of an average size of 2–4 μm and maximum size of 25 μm in the PGM ores .
Highlights Milling parameters of the PGM ore are measured and others back-calculated. Simulated and measured product size distributions were satisfactorily compared. Milling kinetics of the desired size class for flotation were simulated using the parameters. Results show good match between experimental and predicted. Validity of the determined parameters was confirmed through further …
