Abstract:
1. A method of forming molybdenum oxide from material including molybdenum sulfide, the method comprising the steps of: providing a material including molybdenum sulfide; pressure leaching the material including molybdenum sulfide to form a pressure leach discharge comprising pressure leach discharge solids and pressure leach discharge liquid; separating the pressure leach discharge solids and the pressure leach discharge liquid to form a separated liquid and separated solids comprising molybdenum oxide; extracting at least one soluble metal value from the separated liquid to form a loaded stream; stripping the loaded stream using a basic solution to form a stripped solution; separating a molybdenum value from the stripped solution; and recovering the molybdenum value separated from the stripped solution.
