Study on Flotation and Crystal Chemistry of Several Sulfate Minerals
In sodium oleate and salicylhydroxamic acid systems, sequence of floatability of three sulfate minerals is: barite＞celestite＞gypsum, in lauryl amine system is: gypsum＞celestite＞barite. XPS and infrared spectrum analysis are used to find that it is chemical reaction between sodium oleate and three minerals, physical adsorption on the surface of minerals for lauryl amine, and it is chelating reaction between salicylhydroxamic acid and three minerals possibly. Theoretical calculation on chemical bonds in crystal structures of three minerals is carried out, finding that breaking degree of Mn+-O2- in crystal structures of three sulfate minerals is closed related with floatability.
