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. (C) 1997 Elsevier Science B.V.
