Mechanical grinding kinetics and particle packing novel

1. Introduction. Iron ore tailings (IOTs) was the residual solid waste that remained after the extraction of iron from iron ore [1, 2], which was typically deposited in tailings ponds.Leakage or spillage from the tailings pond can result in the release of harmful substances into the surrounding soil, groundwater, and rivers, causing contamination of The grinding experiment was operated with the Anshan type iron ore. The results of the laboratory grinding experiment indicated that the media size ratio, space-filling factor, and material ball ratio had a significant influence on the grinding kinetics of the iron ore sample. (2) The average grinding rate increased with a decrease in media size.An innovative approach for determining the grinding media
