Eric Bain Wasmund, Eriez Flotation Division's global managing director, explained that large mechanical cells are the mainstay for rougher flotation in almost all bulk flotation processes. Increasing the individual cell size and reducing the number creates modest improvements in footprint and operating costs, but it doesn't improve the ...

Flotation circuits use multiple flotation cells in series to recover the maximum amount of desired minerals. Circuits consist of a set of cells called rougher, cleaner, and scavenger, as illustrated in Figure 5. Rougher flotation cells are usually mechanical type and appear first in the circuit, to increase the recovery of the valuable …

A variable in the flotation circuit design is to include column cells in the cleaner circuit in order to improve the gold concentrate quality and to reject insoluble material. Column cells are particularly important when the ore present high content of silicates, carbonates and clays, which affect thickening, filtration and concentrate grade.
