ABSTRACT:
A chemical process for treating metal sulfide materials, such as copper sulfide concentrates, to produce water-soluble metal chlorides and preclude the production of undesirable sulfur oxides. Such a metal sulfide material is contacted with an effective amount of a chlorinating reagent solution at a temperature below the boiling point of the reagent solution. The reaction proceeds until the metal sulfides are converted into metal chlorides and elemental sulfur is formed. The chlorinating reagent solution contains a chlorinating agent having a labile chlorine atom capable of reacting with the metal values to form metal chlorides, and at least one liquid hydrocarbon solvent which is capable of solubilizing both the chlorinating agent and the elemental sulfur produced during the reaction. The metal chloride product, which is insoluble in the reagent solution, is recovered from such solution by conventional means, e.g. by filtration, for conversion into the metal or metals.
