Rock Phosphate Ore Beneficiation Plant Sale
Beneficiation of phosphate rock differs greatly from one deposit to the next, with common methods including screening, grinding, flotation, classification, filtration, and . In general, however, they are all processed via a wet process, resulting in a wet phosphate rock, which must be dried before it can move on to subsequent processing.To develop a means of treating low-grade phosphate rock in order to yield a product high enough in phosphorus content to compete economically with naturally-occurring high-grade rock. As a means to this end, froth flotation has been selected for the bene-ficiation operations. other methods, such as electro-magnetic.Shown advantages on acidic, high-ﬁxing soils. On low-ﬁxing soils, broadcasting and incorpo-rating large P applications before planting can supply P needs for several years. TABLE 2.
