How to Recover Cobalt and Nickel from Copper

2018-12-22 · Grinding to achieve greater liberation was necessary. The copper concentrate from the mill was about 50 to 58 pct minus 400 mesh, or an average particle size of 34 µm. After grinding 30 min in an 8-inch, laboratory steel-ball mill, the average particle size was 10 µm, and after a 45-min grind, the average particle size was 7.5 µm (fig- 3).
