Abstract
A new synthetic reagent containing a mixed aliphatic-aromatic structur e, with a hydrocarbon chain and an aminothiophenol chelating group, ha s proven to be an effective collector for the flotation of chrysocolla minerals. The flotation is optimum in the narrow pH range of 5.5 to 6 , falls sharply at pH 5, and is moderate in the pH range 7 to 11, Infr ared spectra indicate that copper aminothiophenolate chelates are form ed on the surface of the chrysocolla under the conditions of maximum f lotation.
