Flotation is the most widely used beneficiation method for fine materials, and almost all ores can be separated by flotation. Another important application is to reduce ash in fine coal and to remove fine pyrite from coal. The flotation machine is mechanical equipment for realizing the froth flotation process and separating target minerals from ore.

Of the column and ii) a cleaning zone, where the froth rising from the collection zone is washed of the entrained gangue by counter current wash water introduced at the top of the column. Finally, the washed froth overflows from the launder and is collected as the product while the tailings are discharged from the bottom. Commercial flotation.

Combustibles. Coal flotation follows the first order kinetics and rate constant was calculated using the following Eq. 2 (Agar et al, 1980) (2) Where, k is the flotation rate constant, R comb is the recovery of combustibles at time t. The flotation kinetics at different frother dosage is shown in Figure 3. It appears that at higher frother.

Kaolinite, as a mineral in fine coal, has an important influence on the flotation of coal particles. In this study, the effects of ultrafine kaolinite particles on the flotation recovery of coal particles were investigated. Flotation tests were carried out using a mixture of coal particles and different amounts of ultrafine kaolinite particles.

Flotation kinetics tests were conducted on a laboratory flotation machine of 0.5 L capacity. The impeller speed and pulp density were kept constant at 1800 rpm and 60 g L, respectively. An adequate dosage of frother (sec octyl alcohol), 200 g t, was chosen to generate enough bubbles for the flotation of coal.

Machines with large specific surface areas are generally preferred for coal flotation, due to the fast flotation kinetics of coal and the large froth solids loadings. Flotation machines with individual cell volumes of up to 28 m 3 are commonly used due to advantages in terms of capital, operating and maintenance costs. Some manufacturers also offer ‘tank’ machines, which consist of relatively short.
