Flotation Cell - an overview ScienceDirect Topics

The major operating difference between column and mechanical cells is the lack of agitation in column cells that reduces energy and maintenance costs. Also, it has been reported that the cost of installing a column flotation circuit is approximately 25–40% less than an equivalent mechanical flotation circuit (Murdock et al., 1991).

Grau and Heiskanen (2005) had previously found that the size distribution in a number of types of mechanical flotation cell was well-described by a so-called 'upper limit distribution', also referred to as a three-parameter log-normal distribution, given by Mugele and Evans (1951). Liquid transport in a coalescing froth . In these comparative tests, the DO-3500 cell proved itself to be a state ...

mechanical flotation cells by investigating the fundamental gas dispersion mechanisms occurring in the mechanical flotation cell. It is hoped that this approach will lead not only to a practically useful bubble size predictor, but also to a deeper understanding of the microprocesses taking place in the flotation cell which will enable design of more efficient flotation cells.

Comparison of flotation performance between the flotation column and mechanical flotation was carried out to promote the grade and economic value of the graphite ore (15.40% ash content). The ash content of the concentrate of the mechanical flotation was 10.77% at the yield of 79.34%. In contrast, the yield of the concentrate of the column flotation was increased to 88.93% with 10.55% ash content.

Measurement and modelling of gas dispersion ...

The gas dispersion characteristics in mechanical flotation cells have a significant effect on the overall flotation performance. Three major properties that can be measured in characterising the gas dispersion in a flotation cell are bubble size, gas hold-up, and superficial gas velocity. Another property that is equally important in flotation is bubble surface area flux which is calculated ...
