Title:
METHOD FOR SEPARATING MOLYBDENUM, AND METHOD FOR PROCESSING COPPER-CONTAINING MOLYBDENITE
Document Type and Number:
WIPO Patent Application WO/2017/081802
Kind Code:
A1
Abstract:
This method for separating molybdenum separates molybdenum from an acid solution containing copper ions, ferrous ions, and molybdenum ions, wherein ferrous ions in the acid solution are oxidized and the pH of the acid solution is adjusted to 0.5 to 3.0, whereby at least a portion of the ferrous ions are precipitated as a ferrous compound and the molybdenum ions in the acid solution are precipitated as a solid to separate the molybdenum.
