Mining chemicals are widely used in the processing of minerals and separation of the valuable elements. In designing a treatment process, the selection of chemicals is a delicate process that is to ensure the most effective separation and concentration results. Chemical separation processes involve leaching of one or more target minerals.
As a result, its superior separation performance was also validated. 2. Experimental procedure2.1. Materials. The chemical was purchased and used without further purification. All salts such as nickel nitrate, zinc nitrate, and copper nitrate were supplied by Sinopharm Industries. All of the chemicals have purity greater than 99%.
The predominant species in the uranium/sulfate chemical speciation is the neutral [UO 2 SO 4] species.. Uranium removal process cannot be described solely as anionic exchange. • DFT calculations indicate that complexing of the uranium species with the sulfate adsorbed on the resins is more favorable.
