Underground mining is usually by the room-and-pillar mining or longwall mining method ... but the following sequence of steps is typical. ... Froth flotation is a physiochemical process that exploits the selectivity of the attachment of air bubbles to organic coal particle surfaces and in the nonattachment to mineral constituents. Surfactants ...
Underground mining is more complex and more expensive than open-pit mining. Where removing the overburden would be too costly or ineffective to reach the ore, the decision is made to go underground. After open-pit mining is complete, valuable ore can be mined through underground mining methods.
