As shown in the figure (right), a typical flotation flowsheet might include rougher flotation followed by scavenger flotation. The rougher and scavenger concentrates may be reground to a predetermined liberation size and then subjected to two or three stages of cleaner flotation to produce a final flotation concentrate.
processed through the Gold Recovery Plant (GRP) at the end of the project life. The original plant as commissioned plant in 2009 did not achieve design throughput or predicted gold recovery. It has taken a number of years plus additional CAPEX and debottlenecking exercises to improve recovery and achieve design throughput.
