Fine Particle Processing Of Copper Minerals
The oxidation of copper sulfide minerals during grinding …
Clay minerals which are often associated with copper, gold, coal, bitumen and other valuable minerals have a deleterious effect on the mineral flotation process. They are naturally fine-grained with particles of colloidal sizes and may coat the mineral surface in a way similar to iron oxidation species emanating from steel media [10], [11], [12 ...

Entrainment of Gangue Minerals in Froth Flotation
Entrainment is a process by which fine and ultrafine particles are transferred to the flotation froth from the top of the flotation pulp, and eventually discharge to the concentrate product, even when they are not attached to gas bubbles. Therefore, entrainment can be considered as a two-step process, one at the upper layer of the pulp to the flotation froth, and …
