Similar to ore dissolution, flotation reagents themselves may contribute a small portion of water constituents (Slatter et al., 2009), but these constituents can be accumulated in water in an altered or unaltered state during water reuse and eventually reach a concentration high enough to impact flotation performance.

The Concorde Cell is a high-intensity pneumatic flotation cell dedicated to fines and ultrafines. Its development by Professor Graeme Jameson and later on by Metso was driven by two considerations: a reduction in bubble size and an increase in the shear rate and energy dissipation rate increases the particle–bubble collision and attachment efficiencies of fine …

On comparing the flotation rates for copper, generally the flotation rates were higher at 25 ℃ than at 60 ℃. The flotation rates of copper at both 25 and 60 ℃ are within a small range of 0.46–0.55 min −1. The highest copper flotation rate of 0.58 min −1 with R max = 86.27 % was observed for 25 HHL (IS = 0.412 M). Whilst copper was ...
