  • Developing a Bulk Circuit Suitable for Chalcopyrite Pyrite ...

    The chalcopyrite and pyrite losses in the tailing from the rougher circuit were the same for both bulk and sequential roughing (less than 6%). In cleaning (bulk circuit), the effective pH for pyrite depression was about 11.8. The copper recovery was 70% (grade of 20% copper) and the sulfur recovery (pyrite product) was 80% (grade of 36% sulfur).
