Tower Mill - 911 Metallurgist

The major advantage of the Tower mills over the ball mills in regrinding and fine grinding operations is an efficient utilisation of the fine grinding media. The normal top size of media used is 10 - 25 mm but for very fine grinding even smaller media can be used. Tower mills were first introduced in the 1950s as an alternative.

IsaMill - Wikipedia

The IsaMill is an energy-efficient mineral industry grinding mill that was jointly developed in the 1990s by Mount Isa Mines Limited and Netzsch Feinmahltechnik ("Netzsch"), a German manufacturer of bead mills. The IsaMill is primarily known for its ultrafine grinding applications in the mining industry, but is also being used.

Technology Development. • Development driven by inability to efficiently treat fine grained minerals. • Late 1980s, Xstrata required 7. µm grind of Pb/Zn ore for new projects. • Conventional technologies previously tested, 1975-1990. – Too high power consumption to achieve target size. – Ball/tower mills ineffective below 20.

Integrated modeling of grinding, liberation and leaching of gold ores

The main reason for neglecting the exposure properties of gold grains in leaching models, despite its important role in optimization of both grinding and leaching process, is due to the complexity of the estimation of this parameter. Gold grains are distributed in the ore matrix in very low concentrations and usually in very fine.
