Flotation Separation is a way of separating mixtures. It is used to separate substances by whether they float or sink. When a mixture is put into a tube and is stirred, the lighter substance should rise above the heavier substance. The substances are then separated and can be removed separately. next Page Was this helpful? * Yes No Comment

Flotation is used to separate sulfide ores from the impurities in the ore ( gangue ). A detergent is added to the mixture and it is stirred. The sulfide minerals float, while the gangue sinks to the bottom and is removed. This is used in making zinc, where zinc sulfide ( sphalerite) is a major zinc ore.
