Effects of froth properties on dewatering of flotation ...
15-08-2020 A number of studies on copper flotation indicates that froth rheology is closely related to the bubble size and particle fraction on lamellae (Li et al., 2015, Li et al., 2016b). A good characterization of froth rheology will help to understand the froth structure and its effects on dewatering.

Coarse-particle flotation applied to copper sulfide ores
The largest source of copper supply worldwide comes from copper produced through flotation processes. It is estimated that more than 82% of primary copper production comes from concentration by flotation processes. In Peru, the latest mining megaprojects have been concentrator plants (Cerro Verde, Las Bambas, Constancia, Antapaccay, and so on).

Mineral processing - Dewatering Britannica
Mineral processing - Mineral processing - Dewatering: Concentrates and tailings produced by the methods outlined above must be dewatered in order to convert the pulps to a transportable state. In addition, the water can be recycled into the existing water circuits of the processing plant, greatly reducing the demand for expensive fresh water.
