The froth flotation process typically involves a series of multiple flotation cells arranged in a sequential manner. This configuration allows for a step-wise separation of valuable minerals from the ore, with each cell playing a specific role in the overall process [].The use of multiple cells in series enhances the efficiency of the flotation …

The other type of flotation cells is a column cell. Column cells are tall round tanks that use compressed air to create air bubbles via spargers or cavitation tubes. These cells are used to perform mineral separations. Column cells do not use mechanical agitation (impellers). Mixing is achieved by the turbulence provided by the rising bubbles.

Flotation behaviour of minerals. To expand the application of the RFC from the coal industry to a wider range, understanding the flotation behaviour of minerals in the RFC is the key. The RFC has shown a good performance in coal flotation and it can recover both coarse and fine coal particles at a high throughput.

Results show that our flotation machines operate on exceptional grade recovery curves, with respect to coarse and fine particle recovery. The remarkable performance of our machines is related to flotation-favourable hydrodynamics, which produce higher active cell volumes, provide longer residence times, and complement froth removal.
