Flotation of phosphate Phosphate ore is the most important source of phosphorus in fertilizers. To supply the phosphoric acid plant with phosphate a high grade of phosphorus is essential as well as reduced levels of impurities such as magnesium iron and aluminum oxides. Flotation is one of the key beneficiation methods.
Apr 16 2019 In addition the finer particle size the better iron removal effect. Because the fine-grained silica sand contains high amount of iron-containing impurities. When the original silica sand contains more impurity minerals it is impossible to purify silica sand into high-purity sand by scrubbing deliming and magnetic separation. 4.Flotation
