America is blessed with abundant low-cost natural gypsum. There is also an abundance of flue gas desulfurization gypsum produced as a by-product of coal-fired power plants. As a result, the market for the phosphogypsum generated by the chemical processing of phosphate rock has traditionally been limited.

17.3 MINERAL PROCESSING AND BENEFICIATION PROCESSES It is the first process that is done to separate useful minerals from the waste rock or gangue. This produces a more concentrated material for further processing. Concentrating the needed minerals in the mined material is known as the beneficiation process. Sometime, the beneficiation at the ...

Abstract: Agriculture has failed to be sustainable several times in the history of the world because of soil failure (Rush, 1987). Irrigated land eventually leads to sodicity and salinity unless extreme care is taken. Gypsum is a key ingredient for the maintenance of agriculture on many types of soils and over a wide pH range including sodicity. Waste-product gypsum is available in a large ...
