Effect of grinding media and NaHS on copper recovery at …
The addition of NaHS after grinding using mild steel rods increased the froth stability by increasing froth mineralisation, thus increasing the flotation kinetics of the copper minerals. When stainless steel grinding media was used, the copper flotation recovery was very high (>90 % in the rougher stage) without the addition of NaHS, so its use ...

The Magotteaux Mill®: investigating the effect of grinding media …
Invariably changing the grinding media type from forged to high chrome produced a shift to less reducing pulp conditions and a positive change in the flotation response. A typical example of the improvement in the flotation performance is illustrated in Fig. 3 (Ward and Grano, 1999). These data indicated that when high chrome grinding …

The type of grinding media has a great effect on mineral flotation. Stainless steel media minimises the amount of iron oxidation products originated from grinding media and therefore the lignosulfonate base polymer F-100 may mitigate the negative effect of clay minerals resulting in the improved copper and gold flotation.

The influence of copper ore lithology on the grinding media wear
Based on the performed investigations the following conclusions are given: 1. The largest share in the grinding media wear of the three "pure" lithological ore components was sandstone. Percentage average share in the wear for sandstone (S), dolomite (D) and slate (Sl) is as follows: S = 74.4 %, Sl = 15.7 %, D = 9.9 %.

Grinding Balls and Other Grinding Media: Key consumables
Tower Mills: 0.5"-1.5" grinding balls are recommended. The normal top size of media used is 10-25mm, but even smaller grinding balls can be used for very fine grinding. Isa Mills: <0.1" grinding balls are recommended. The Isa Mill is more efficient when using small media (i.e. high-chrome steel balls).
