In this study, industrial lithium-ion battery (LIB) waste was treated by a froth flotation process, which allowed selective separation of electrode particles from metallic-rich fractions containing Cu and Al. the experiments, recovery rates ~80 98.8% for cathode active elements (Co, Ni, Mn) graphite were achieved, respectively. The recovered metals fraction subsequently used in high-temperature...

Multivariable regression and artificial neural network procedures were used to modeling of the input power and gas holdup of flotation. The stepwise nonlinear equations have shown greater accuracy than linear ones where they can predict input power, and gas holdup with the correlation coefficients of 0.79 thereby 0.51 in the linear, and R2=0.88 versus 0.52 in the non linear, respectively. ...

Understanding the hydrodynamics of three-phase stirred tanks, such as froth flotation cells, is paramount for characterisation turbulence, stability and performance. Although positron emission particle tracking (PEPT) known its effectiveness in measuring particles opaque, high solid content systems, it has not been widely used characterising liquid phase. This work presents a new, neutrally buo...

Temperature variations could potentially impact flotation performance, leading to operational and economic issues. Several historical currently operating plants across Canada have reported seasonal metal losses as one of their major challenges. Improvements in efficiency at cold temperatures are important for the sustainable development industry, especially view expanding mining operations nort...

Knowledge of surface free energies (and its components) between two entities is important. They dictate not only the strength of the interaction, but also control the processes such as the stability of aqueous colloidal suspensions, the dynamics of molecular self-assembly, wetting, spreading, deinking and adhesion (1-4). Many of the mineral processing techniques, e.g. froth flotation, selective...
