The most important part of the crushing process
The production process comprises 3 stages of crushing, followed by closed-circuit grinding, flotation, separation, thickening, filtration and tailings management. The mine processes 105,000 tons of ore per day, yielding more than 438,000 tons of copper concentrate per year
According to Alejandro Gámez, Plant Manager at Mexicana de Cobre, the tertiary stage is the most important part of the crushing process. In this final stage of crushing, twelve 84” Hydrocones crush the ore into a -½” feed for the grinding mills.
“By feeding the primary grinding mills with particles smaller than half an inch, we make sure that the grinding media inside the mills can break the ore efficiently, reducing the amount of recirculating feed,” he explains.
