Flotation Circuit an overview ScienceDirect Topics

True flotation was described by first-order kinetics with distributed rate constants, and entrainment was modeled by taking into account water recovery to concentrate. A genetic algorithm was applied for the optimization problem. However, the computation costs were very high for a two-stage flotation circuit with three species.

Use of water soluble polymers in coal flotation circuits

The objectives of the test were to reduce the ash in the clean coal, increase the percent recovery of the coal and reduce the amount of fuel oil being used in the flotation circuit. The polymer used in these tests was a 20 percent by weight aqueous solution of a homopolymer of dimethyl diallyl ammonium chloride having a molecular weight of 40,000.

Physical and chemical interactions in coal flotation

2003-9-29  Coal flotation is a complex process involving several phases (particles, oil droplets and air bubbles). These phases simultaneously interact with each other and with other species such as the molecules of a promoting reagent and dissolved ions in water. The physical and chemical interactions determine the outcome of the flotation process.

Applying High Salinity Water in Flotation-A Review

2020-6-18  Flotation of coal using sea water The reason that sea water has been applied for coal flotation is mainly because in 1920 some coals were reported to be readily floated in sea water without the addition of reagents (collector and frother). In 1930’s, the flotation of coal using sea water was further investigated by Russian researchers [8].

Flotation Process an overview ScienceDirect Topics

The residence time, pulp volume and flotation kinetics play a vital role in determining the selection of the number of cells required in a flotation circuit. To prevent loss of floatable coal along with tailings, it is advisable to put cells in series. Fig. 5.34 indicates the coal recovery through multiple cells (in series) in a bank.

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).
