DESIGN AND PERFORMANCE ASPECTS OF COAL FLOTATION

Flotation is a complex multifaceted process that can be separated into three main areas: the coal, the chemistry and the machine, as shown in Figure 1. To solve plant issues it is important to understand how different factors within these areas affect and control flotation performance for a particular system. Factors within the coal and

Physical and chemical interactions in coal flotation

Sep 29, 2003· 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.

Coal drying. Coal preparation plants that employ fine coal cleaning by froth flotation can produce an unacceptable amount of moisture in the product. Thermal drying, in which the wet coal is dried in the hot gas generated by a coal-or gas-fired burner, is used in some plants to reduce the moisture content. Refuse and tailings management.
