The flotation orp normally is from 500 mv to 600 mv, depending of the copper sulphide species. depending of the ph you will have h2s gas emmision to the ambient that you can have controlled in float cells closed and with scrubbers with caustic solution (10) achieving in some cases close to approx 0 ppm of h2s to the plant site ambient.

The froth collected from a series of rougher cells is then passed to a set of cleaner cells to further raise the copper sulfide concentrations (fig. 13.5). the ganguerich underflow from the rougher cells is passed through a series of scavenger cells to collect any residual copper sulfide values not picked up by the rougher cells.
