A ball mill also known as pebble mill or tumbling mill is a milling machine that consists of a hallow cylinder containing balls; mounted on a metallic frame such that it can be rotated along its longitudinal axis. The balls which could be of different diameter occupy 30 50 % of the mill volume and its size depends on the feed and mill size.
It is noted that the ball milling also enhanced the adsorption ability of biochars for other organic contaminants (, tetracycline and reactive red) and heavy metals (, Pb and Ni) ( Table 3).
In the mining industry, the comminution stage can represent up to 70% of the energy consumed in a mineral processing plant [1,2,3,4,5].With ballmill grinding being one of the most energyconsuming techniques, setting the optimal values of the operational and mineralogical parameters for efficient grinding is a key target in mineral processing plants [6,7,8,9,10].
