A comminution technology that is capable of surface cleaning as well as particle fracture is stirred milling. Stirred milling technology is suitable for reprocessing coarse and finegrained mining waste as it uses an attrition mechanism to grind the material (Altun et al., 2013; Wills and Finch, 2016; NapierMunn et al., 1996), removing hydrophilic surfaces and reducing particle size.

Based on the media, two types of ball milling, namely dry and wet, are classified. As the name suggests, wet milling disperses the material in liquid media to form a slurry, while dry milling relies on particle contact. Although dry and wet milling can both be adapted for various materials, certain restrictions do apply.

Wet milling of solids in ball mills is more intensive than dry milling. The reason for this has been explained by investigators [14] in different ways. Thus, the great effectiveness of wet milling is explained [1, 2] by the saturation of the unsaturated bonds of the surface of the material by water molecules.
