Abstract
To achieve maximum efficiency in any purification stage, the flotation should be continued until
the concentrate grade reaches the feed grade. During sampling from rougher cells of the Iranian
Sarcheshmeh copper concentrator plant 1, it was revealed that the concentrate grade of the last five cells
of rougher circuit was close to feed grade. Therefore, it was suggested that the concentrate of the
aforementioned cells be mixed with rougher feed. In this study, one of eight rougher circuit rows was
selected and evaluated. The floatability tests were performed to compare the flotation behaviour of
rougher feed and mixture of concentrate of the last five cells with rougher feed in the laboratory scale
by a tree analysis process. The results showed that mixing of rougher last five cell concentrate with feed
has a detrimental effect on flotation efficiency that leads to a 3% decrease in recovery. It was also
observed that with grinding of this concentrate, recovery can be improved.
