FLOTATION SEPARATION OF ARSENOPYRITE FROM PYRITE ...

In the case in which the pyrite rougher is operated with a high level of utilization of the collector, so that the tailings from the pyrite rougher are substantially free from arsenopyrite, and substantially all the arsenopyrite reports to the pyrite rougher froth concentrate, the tailings from the Py cleaner stage provides the final arsenopyrite concentrate and is collected separately as …
