The mine is an open pit, truck/shovel operation. The ore is crushed at the rim of the pit and conveyed through a kilometre tunnel to a coarse ore stockpile at the mill. It is then processed utilizing a SAG mill, followed by ball mill grinding and flotation to produce separate copper, zinc, molybdenum and lead/bismuth concentrates.
Isa Mill Test The IsaMill a transformation in grinding technology, provides high intensity fine grinding for maximising mineral liberation. The IsaMill is a grinding technology based on high intensity stirred milling, using inert media that was developed for the processing of fine grained ore bodies.
201423 MILL CONTROL: BALL MILL CONTROL EXAMPLE Process Description The copper concentrator in Pinto Valley, Arizona processes a % grade copper ore from a nearby open pit mine. The unit operations consisting of crushing, grinding, and flotation process about 65,000 tons of ore per day in six overflow ball mills. Chat Now

Zinc smelting is the process of converting zinc concentrates (ores that contain zinc) into pure zinc. Zinc smelting has historically been more difficult than the smelting of other metals, iron, because in contrast, zinc has a low boiling temperatures typically used for smelting metals, zinc is a gas that will escape from a furnace with the flue gas and be lost, unless .

ABSTRACT Mill filling is an important operational parameter in a SAG mill circuit and by its control and optimisation it can produce significant improvements in production capacity and energy efficiency. However, it is industry practice to report mill load as the total output given by load cells, o...
Apr 11, 2018· After the lunch break Marko Hilden, of the JKMRC, Australia, presented a new SAG mill power model which recalibrates and extends the wellknown Morrell power model for SAG and ball mills. The model estimates the influence of slurry filling, including when the mill is slurry pooling, and predicts a peak power draw between and voidfill ...
