Continuous control of the final grinding product size is important to optimize gold liberation for gold milling operations. In addition, the live monitoring of the final product particle size leads to a maximum grinding circuit throughput.

Primary Crushing SpringerLink

This (Truscott) is “the whole operation of reducing the crude ore to the fineness necessary for mechanical separation, or for metallurgical treatment” 1 It is usual to make an arbitrary division of comminution into convenient stages. Primary crushing brings runofmine ore down to a maximum size of the order 4″ to 6″ in average

benchmarked the energy consumption of open cut iron ore and gold mines. In investigating iron ore in an open cut mine, it was reported that there was potential to reduce the mining costs (based on energy savings) by 36% and milling costs by 47%. For gold mining this estimate was reduced to a staggering 53% for milling. Examples of Energy Events

ROCK CRUSHING METHOD AND SEPARATING GOLD

Gold ore separation uses comminution techniques to break down the excavated rock, but the material hardly looks like a lustrous yelloworange metal. In order to properly free this rich element from the rock, the crushing stage has to be followed by a chemically active stage, such as the cyanidation process or the carbon in pulp release
