Forward flotation was conducted, the coal was recovered on the float while the gangue minerals were recovered in the sinks. Distilled water and 500g of the sample were added in a 1.5-liter Leeds Barker flotation cell shown in Fig. 1 to create a slurry for the flotation experiments. Fig. 1: Leeds Barker flotation cell
1.1.3 Flotation Machines Froth flotation is performed in machines specifically designed for that purpose. There are two basic types of flotation machines and adaptations of these machines. Conventional (mechanical) and column flotation cells are the two types of flotation machines used in flotation (Figure 2).
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 …

Efficient flotation of coarse low-rank coal is essential for enhancing energy utilization in the mineral processing industry. As the beneficiation equipment scales up, the precision of particle size classification before flotation decreases, leading to a higher coarse particle content in the feed, which poses significant challenges to traditional flotation processes.
Flotation stands out as a successful and extensively employed method for separating valuable mineral particles from waste rock. The efficiency of this process is subjected to the distinct physicochemical attributes exhibited by various minerals. However, the complex combination of multiple sub-processes within flotation presents challenges in controlling this …

A flotation machine has to fulfill three basic functions: (I) Sufficient and wide range of bubble (size range of 0.5–2 mm) which needs a powerful and functionable air-blower and sparger ; (II) Reaching the perfect dispersion of solid materials in order to enhance the chance of bubble paricle collision which needs an efficacious rotor/stator ...
Each cell of the flotation machine contains an impeller, which is a rotating device responsible for stirring the slurry. The impeller creates a turbulent environment in the cell, ensuring thorough mixing of the reagents and ore particles. Air Supply. Air is introduced into the flotation cell through various mechanisms, such as blowers or spargers.
Generally, the conventional flotation machine may involve four dynamic areas: agitating and mixing zone, transport zone, separation zone and froth zone. The properties of different dynamic zones in air force flotation cell are elaborated as an example combined with the flotation process of mineral particles, as shown in Fig. 2.4.
