A comparison of two flotation circuits
All mathematical models of flotation systems are approximations, their usefulness only being if something of practical value is learnt. We argue that this is the case here: that the open R-C-CS structure in addition to the isolation of roughing from cleaning may also provide greater separation over its closed cousin.

Modelling of entrainment in industrial flotation cells: Water recovery
Based on the solids suspension data collected from different industrial flotation cells at different mine sites, it is found that CF i can be described as an exponential function of the particle size regardless of cell size. The CF i value for the fines (i.e., −38 μm) is close to 1, while for the coarser particles, the CF i values depend on the cell operating conditions especially the …

MLA-based sphalerite flotation optimization: Two-stage roughing
In generally, rougher plays a decisive role on the overall flotation process. To investigate roughing behaviors of the sphalerite, bench-scale flotation tests were performed using an XFD machine which was equipped with a 1.5 L flotation cell. Representative feed slurry was sampled from the flotation plant.
