A DEM numerical modelling approach to simulating size segregation of media in a stirred mill and effects on grind characteristics by Sievers, Wilco

“…Comminution is an important operation in the minerals processing industry. In both traditional and stirred mills, single-sized grinding beads are used, along with multiple passes through the mills, to achieve a sufficient size-reduction ratio. …”

The effect of flotation reagents on the coagulation and dewatering of flotation tailings by Chidzala, Unaswi

“…The study investigates coagulants (e.g., Fe2⁺ salts), that operate by charge neutralisation, and flocculants (e.g., polyacrylamides), that work through polymer bridging or patch processes. Systems which comprise flocculants or coagulants demonstrated higher settling rates, achieving turbidity reductions beyond 500 NTU/min within the initial five minutes, significantly exceeding the performance of systems utilising of only collectors or depressants. …”
