ABSTRACT The commonly used SAB, SABC and run-of-mine (ROM) ball mill circuits can achieve high throughputs with good operating stability. However, these circuits consume a substantial amount of grinding media, which can have a substantial impact on the OPEX and the ‘carbon footprint’, specifically w...

ABSTRACT In looking to the future of mineral processing the focus is typically on improved processing units. Basically it is a search for an elusive wonder machine that could revolutionise the economy of mining: the sorter that strips 50% of the ore with only a few % loss of value; the comminution...

Comminution accounts for approximately 30 to 40% of the energy consumed on an average mine site (DOE, 2007) and somewhere from 4 to 9% of Australia’s total energy consumption (Tromans, 2008). Additionally, if one includes the energy embodied in steel grinding consumables, this may increase comminuti...
