Method for the depressing of hydrous, layered silicates
This patent describes a method for the beneficiation of value minerals from an ore containing the value minerals and hydrous, layered silicates with selective rejection of the hydrous, layered silicates. It comprises: providing an aqueous pulp slurry of finely-divided, liberated ore particles; conditioning the pulp slurry with an effective amount of hemicellulose to selectively depress the hydrous, layered silicates, a mineral collector and a frothing agent, respectively; subjecting the conditioned pulp slurry to froth flotation to produce a froth containing beneficiated value minerals and a resultant pulp slurry containing the depressed hydrous, layered silicates; and recovering the beneficiated value minerals from the froth.
