| Abstract: |
| This paper performs a research on process mineralogy of a porphyry copper-molybdenum ore containing arsenic in Peru, by which the mode of occurrence of arsenic, copper, molybdenum in the ore is investigated, thus the mineralogy material for the ore of this type is enriched and an analysis on the mineralogy factors which influence the mineral processing targets is carried on. The results of process mineralogy show that the oxidation rate is quite low in the ore of this type, and the copper and molybdenum are easy to acquire a high recovery during mineral processing circuit, thus it is easy to achieve more ideal mineral processing targets. However, the arsenic in the ore is also of remarkable concentration in the copper-concentrated ore, more attention should be paid on the trend of tennantite in mineral separation process and produce high arsenic copper-concentrated ore by take full advantage of the small difference in the floatable property between the tennantite and chalcopyrite. |
