Case Studies | Mineral Processing

Furthermore, the customer wanted to add the pure oxygen down the agitator shaft in both the pre-aeration and CIL. Most of the oxygen is added into the pre-aeration tanks. Agitation in the CIL tanks will chip the activated carbon and these fine carbon particles (loaded with gold) will not be collected by the screens that are used.
