A copper collector may also be added at this point. The pulp progresses to the flotation cells. The frother and copper collector are usually added to the pulp just before the roughers. Additional copper collector is often added to the scavenger flotation cells and may be added at several other points. To facilitate the presentation of the modal data, the cleaner circuit of this case concentrator was separated into three operations. The first cleaner circuit, which includes the cleaner-scavenger bank is discussed first, this is followed by a discussion of the operation of the column cleaner circuit. Finally, an analysis of the overall cleaner circuit operation is presented.
