Power input and flotation time are the two key factors influencing the efficiency of the fine coal flotation process. A new two-stage process is proposed in this investigation for intensifying fine coal flotation. The flotation process is divided into two parts: lowering energy input in the first stage and raising energy input in the second stage.

Li et al. [12] optimized the energy input in slime flotation under the same or similar total energy input, wherein clean coal with high combustible matter recovery and good quality can be obtained when energy input is low in the early stage of flotation and high in the later stage. However, the majority of these studies have concentrated on ...

Additionally, the use of high frother concentration can result in persistent and too stable froth formation, leading to overflow in the flotation cells, pumping problems and handling difficulties in the flotation concentrator (Bournival et al., 2017a, Wei et al., 2014). As a consequence of this significant influence of frothers on the overall ...
