Agitation - an overview | ScienceDirect Topics
Agitation leaching is used for oxide minerals that have rapid leach kinetics, such as carbonates, and reasonable grade (0.8%–5% Cu). It can be applied to ores or to milled tailings from other leach circuits. This method is widely used in the African Copperbelt (Reolon, Gazis, & Amos, 2009; Roux, van Rooyen, Minnaar, Robles, & Cronje, 2010).
