There are various designs of laboratory-scale flotation cells which can be used to perform the laboratory batch flotation tests. My preference is to use a bottom driven laboratory cell allowing impeller speed and air rate adjustment, an example of which is shown in Figure 1. This type of cell, used with a fixed depth

Flotation is both a science and an art. It brings together many complex variables. Such basic factors as knowledge of mineral structure, chemical reagents, pH of mill water, pulp density, temperature, technical skills of the operator, the dependability of the flotation machine, as well as a host of other factors which affect the flotation of ...

Flotation utilizes the fact that the metalliferous ore particles, and the gangue minerals have different interactions with water. Fundamentally floatation relies on the fact that hydrophobic ore particles and hydrophilic gangue particles can be separated. Hydrophobic means water fearing and hydrophobic substances fundamentally repel water. Hydrophilic means …
