    摘要: The invention provides a hydrometallurgical process for the recovery of metals. In particular, an aqueous feed solution originating from acid leaching is provided. The aqueous feed solution contains nickel and/or cobalt ions. The pH of the solution is maintained at a level between about 2 and 6. The aqueous feed solution is contacted with a water-immiscible organic phase containing an extractant to load the nickel and/or cobalt metal ions to form a metal-bearing organic phase. The extractant has at least one organic soluble dithiophosphinic acid, alkali, alkaline earth metal or ammonium salt thereof. The aqueous feed solution has sufficiently low levels of chromium (VI) ions, iron (III) ions and copper ions to allow repeated use of the extractant. The metal-bearing organic phase is then separated from the metal-containing aqueous feed solution. Finally, after separation from the aqueous feed solution, the metal-bearing organic phase is contacted with an aqueous strip solution to recover the loaded nickel and/or cobalt from the metal-bearing organic phase.

    摘要: The invention provides an autoclave configuration for pressure leaching lateritic ores at elevated temperatures. The autoclave configuration includes at least one primary autoclave. The primary autoclave includes a slurry inlet port for receiving slurries of lateritic ore from a lateritic slurry supply, an acid inlet port for receiving leaching acids, an agitation means for agitating the slurries of lateritic ore, and an outlet port for removing partially leached slurries of lateritic ore. A multi-compartment autoclave follows the primary autoclave. The multi-compartment autoclave is divided into at least two chambers connected in series. The chambers contain a means for agitating the partially leached slurries and divider walls for separating the chambers. An inlet port is connected to the first of the chambers for receipt of the partially leached slurries. An outlet port is connected to the last of the series of chambers for removal of the finally leached slurries. A bypass conduit is connected to the lateritic slurry supply and the multi-compartment autoclave. The bypass conduit is for periodically isolating the primary autoclave for removal of scale while leaching lateritic ore in the multi-compartment autoclave.

    摘要: The invention provides a method of forming copper arsenate. Copper and arsenic are leached into a treatment solution maintained at a pH level of about 2 to 5 in the presence of at least one impurity. An oxidant is added to the treatment solution to oxidize the copper and arsenic. A copper arsenate compound is precipitated from the solution as copper arsenate. Preferably, the copper arsenate is then releached in a purification solution. The molar ratio of copper to arsenic is adjusted to a level of at least 2. The pH of the purification solution is then increased to precipitate copper arsenate having a decreased concentration of said at least one impurity. Impure copper arsenate may be suspended and reacted in a recrystallization solution preferably having cupric ion. The pH of recrystallization solution is adjusted to a valve between about 1 and 4.5.
