In response to the Natural Resources Canada "Crush It Challenge," Corem partnered with the University of British Columbia and led a project to develop and demonstrate the use of high-pressure grinding to replace the workhorse of the industry, wet ball milling. Two plant case studies, a small tonnage gold recovery operation and a large …
This ball mill will be sent to Chile for grinding the copper ore. After the cooper ore crushing to be 6mm, they are will be feeding into the ball mill to gridning 200 mesh up t0 70%. This ball mill will be close circuit with a hydrocyclone.
The magnitude of the difference was slight for Ball Mill-1 (Fig. 11), but it is more obvious for Ball Mill-2 (Fig. 12). Improved fines generation in Survey 2 can be attributed to the increased solid content of the ball milling operations. For both of the ball mills, Survey-2 had higher solid content than Survey-1.
