These collectors adsorb on the surface to render minerals such as chalcopyrite hydrophobic. Figure 1. Laboratory froth flotation machine.

Froth flotation as it is known today is the process that had its beginnings 100 years ago in Australia, but a graphite flotation process preceded it by nearly three decades. As stated by Sutherland and Wark in 1955: The brothers Bessel (1877) patented a true flotation process for the concentration of graphite ores.….

Abstract. It is not easy to convey, in a few words, the enormous importance of the froth flotation process to the economy of the whole industrial world. It may suffice, for the present article, to quote rough estimates of the quantity of crushed ore which is treated annually by flotation — 2 x 10 9 tonnes — and the proportion of base-metals ...

A light mineral such as coal (density circa 1.4) can be floated at 10 mesh, provided the bubble system on which it is borne is developed as a quiet layer of froth. Random changes of direction, acceleration, and collision may tear too large a particle out of its bubble. At the other end of the flotation size-range, the surface characteristics of ...

Over the past few decades, the need to process more minerals while lowering capital costs has led to an increase in the size of flotation cells, e.g., 0.03 m3 to 1000 m3. However, this increase has created new challenges in the operation and design of industrial flotation cells, particularly in terms of froth removal, because the distance the froth must …

Little work has been reported on the flotation performance of Great Dyke ore. Nashwa (2008) reported on the effect on SIBIX and SIBIX-TTCs blends, but most of the work that has been reported is based on Bushveld Complex ore. Interaction effects between aeration rate and froth have been reported by Venkatesan and Harris (2014).
