Grinding media have significant influence on the flotation of chalcopyrite and pyrite. This effect is mainly related to the change in the surface properties of chalcopyrite and pyrite. This paper investigates the influence of steel ball and nano-ceramic ball grinding on the floatability of chalcopyrite and pyrite. Flotation results, as well-scanning electron microscopy (SEM), X-ray ...

2021-4-9 · The use of small diameter media is favored because it results in a large surface area to weight ratio. Also, liner wear decreases as media diameter decreases. However, there is a limit to how small grinding media diameter can become. For one thing, smaller diameter media are more expensive per unit weight.
