Although it was developed nearly 50 years ago, Bond‘s method is still useful for calculating necessary mill sizes and power consumption for ball and rod mills. This paper discusses the basic development of the Bond method, the determination of the efficiency correction factors based on mill dimensions and feed characteristics, and the application of the results to designing grinding circuits.

However, the results suggested that it seems more promising to use the SWAT to determine the abrasion breakage component and to calculate the breakage function of the small particles (below the inflection point), a function that otherwise would be unattainable in the DWT.En minéralurgie, le broyage est l'opération durant laquelle le minerai ...

Lateritic iron ore has not been used effectively due to excess content of multiple metals. In this work, separation of aluminium from a high-aluminium lateritic iron ore was achieved by the process of ‘direct reduction with sodium sulfate-magnetic separation’, with a powdered direct reduced iron (DRI) produced.
