Manganese metallurgy review. Part II: Manganese separation and recovery
Applications of SX for manganese separation/removal. Manganese is closely associated with zinc ores and nickel–cobalt laterite ores and leached together with these metals. Solvent extraction plays an important role in separation of these metal values from manganese, in which manganese is left as an impurity in the raffinate.
Review of the reagents used in the direct flotation of phosphate ores
Beneficiation of low-grade phosphate deposits through direct froth flotation has captured more attention to satisfy the future needs of phosphorous industry. This is owing to the excessive consumption of the global reserves of high-grade phosphate deposits. Phosphate flotation using mixed collectors has been proved to give greater selectivity and high …
