2020-8-15  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.

Advancement of the Hydrophobic-Hydrophilic Separation

Froth flotation has long been regarded as the best available technology for separating fine particles. Due to limitations in particle size with froth flotation, and high downstream dewatering costs, a new process has been developed called the hydrophobic-hydrophilic separation (HHS) process.
