coal washing | encyclopedia

coal washing is accomplished by one of two major processes by density separation or by froth flotation. both processes depend on the fact that the particles of which a coal sample are made have different densities. when water for example is added to the sample particles sink to various depths depending on their densities.

zinc smelting - wikipedia

zinc smelting is the process of converting zinc concentrates (ores that contain zinc) into pure zinc. zinc smelting has historically been more difficult than the smelting of other metals e.g. iron because in contrast zinc has a low boiling point.at temperatures typically used for smelting metals zinc is a gas that will escape from a furnace with the flue gas and be lost unless specific ...

flotation machine - an overview | sciencedirect topics

froth flotation depends on differences in surface properties between coal and shale. air bubbles are generated within an aqueous suspension of fine coal with a solids concentration of less than 10%. the hydrophobic coal particles attach to the air bubbles and are buoyed to the top of the froth flotation cell where they are removed as froth.
