— Under the same ball milling power (or output), the short-cylinder ball mill has a more substantial impact than the longer-cylinder type. However, the production quickly fluctuates due to the short residence time of the material in the mill, and the operation is more complicated.
highest recovery obtained in the first mill-float stage was about 75.8%. Flotation tailings were milled and floated again in a Mill-Float-Mill-Float (MF2) configuration. After re-grinding and floating again, the highest recovery (cumulative) obtained was 92.2% which represented a significant improvement in the copper recovery.
