5 Processes involved in ore reduction ... The copper extraction process begins at an open cut mine where Copper Ore is blasted and ... conveyor it is transported to a Ball Mill to have its particle size reduced further. During , ENG450 ENGINEERING INTERNSHIP MURDOCH UNIVERSITY AUSENCO SCHOOL OF ENGINEERING AND ENERGY .
Then, in the finer size ranges, where something like a HIGmill or a SMD are used, its all about energy efficiency. Its much more efficient to grind to very fine or ultra-fine levels using these technologies that have very small media than in a ball mill where a lot of the energy is wasted in lifting the media, as opposed to grinding.
Copper and gold processing milling ball mill gear we sent a substantial amount of quartz gold ore to a mill for processing after a couple hundred tests on the material an average grade was calculated after milling for several days the mill says there is way less gold in the ore than what had been estimated once milling began samples were take .
A Chile copper mine had a Vertimill and a Ball mill in a regrind circuit, allowing for the mills to be audited and compared. The Vertimill acheived the same grind with 44 less energy than the ball mill using while 26 mm forge steel balls. The Vertimill was then charged with Millpebs less than
