Gravity separation is an industrial method of separating two components, either a suspension, or dry granular mixture where separating the components with gravity is sufficiently practical: i.e. the components of the mixture have different specific weight. All of the gravitational methods are common in the sense that they all use gravity as the dominant force. Gravity separation is used in a wide variety of industries, and can be most simply differentiated by the characteristics of the mixture to be separated - principally that of 'wet' i.e. - a suspension versus 'dry' -a mixture of granular product. Often other methods are applied to make the separation faster and more efficient, such as flocculation, coagulation and suction. The most notable advantages of the gravitational methods are their cost effectiveness and in some cases excellent reduction. Gravity separation is an attractive unit operation as it generally has low capital and operating costs, uses few of any chemicals that might cause environmental concerns and the recent development of new equipment enhances the range of separations possible.

Famous quotes containing the words gravity and/or separation:
“Grown beyond nature now, soft food for worms,
They lift frail heads in gravity and good faith.”
—Derek Mahon (b. 1941)
“The scholar was not raised by the sacred thoughts amongst which he dwelt, but used them to selfish ends. He was a profane person, and became a showman, turning his gifts to marketable use, and not to his own sustenance and growth. It was found that the intellect could be independently developed, that is, in separation from the man, as any single organ can be invigorated, and the result was monstrous.”
—Ralph Waldo Emerson (1803–1882)
