| Outline of Final Research Achievements |
We clarified that the copper sulfide minerals, high arsenic containing copper minerals, and molybdenite can be separated by flotation using oxidation of the mineral surface. In addition, it was shown that high arsenic containing copper mineral which is difficult to separate by flotation, can be separated from copper sulfide minerals by newly developed heat treatment / magnetic separation method. As a heating method, microwave heating was also effective. In addition, we revealed the mechanism of scorodite formation and Cu recovery by bioleaching and/or chemical leaching of high arsenic containing copper mineral. We suggested an inexpensive carrier microencapsulation method of sulfide minerals for suppressing acidic mine drainage using hydrothermal treatment liquid of low rank coal and showed it is effective. Based on these results, the optimal process flow for mineral processing of high arsenic containing copper minerals is proposed.
