The overall objective of this research effort is to improve the efficiency of fine coal flotation in preparation plants above that of currently used conventional cells. In addition to evaluating single-stage operation of four selected advanced flotation devices the project will also evaluate them in two-stage configurations. The project is being implemented in two phases. Phase 1 comprises .
The book examines coal processing surface forces and hydrophobicity process improvements and environmental controls dewatering and drying gravity separations industrial minerals flotation base metal flotation flotation equipment and practice process reagents magnetic and electrostatic separations modeling and process control and .

Moatizes main branded products are the MLV premium hard coking coal and Moatize Low Vol Premium hard coking coal but there is operational flexibility for multiple products. The optimal product portfolio will come as a result of market trials. Coal from the mines is currently processed at a CHPP with a capacity of 4000 metric tons per hour.
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.
Dawson Coal plant is the largest coal handling and preparation plant CHPP in Australia. The raw coal system will accept coal from three separate mine sources delivered by an overland conveyor system with the CHPP processing at 2000 tonnes per hour in two stage mode and up to 3400 tonnes per hour in single stage mode.

Flotation is a selective process and can be used to achieve specific separations from complex ores such as lead-zinc copper-zinc etc. Initially developed to treat the sulphides of copper lead and zinc the field of flotation has now expended to include platinum nickel and gold-hosting sulphides and oxides such as hematite and cassiterite oxidised minerals such as malachite and cerussite and non-metallic ores such as fluorite phosphates and fine coal.
