  • Coal Preparation Technology Coal Preparation TechnoMine

    The basic principle for coal preparation is to first liberate the coal particles from the gangue (quartz) and then, by applying different water based techniques, separate the coal particles and gangue particles. The most common techniques for coal preparation are gravity separation and flotation. There are four basic types of

    How Gravity Tables Work. A gravity separator, or air table, is commonly used to separate particles by weight and density. A separation can be used for any dry material as it moves on a "fluidized" bed of air across the table. The separator creates eccentric motion and has an adjustable uphill tilt which separates heavier
