flotation circuit simulation The R max-slope and K avg-slope parameters presented in Table 1 provide the link between drill core flotation testwork results and FLEET flotation circuit simulation on a block-by-block basis for design and/or production forecasting studies. A geometallurgical model is created by following the steps
The D+E flotation circuit is operated in a slightly different manner to the A, B, C circuits, with the regrind cyclone overflow feeding two parallel flotation columns (2.13 m diameter). The circuit configuration also allows for tailings from one column to be reground in closed-circuit with the second column acting as a recleaner.
To validate the predictive ability of the model a different circuit layout was configured, corresponding to "Test 3 Circuit B" in (Harris, 2000).The circuit layout is shown in Fig. 2, and is referred to as "Circuit B" for the remainder of this paper.A full pilot-plant dataset for this layout was available, using the same feed and under similar operational …
In this way, the flotation circuit enables energy savings plant wide. Additionally, coarser grind size facilitates dewatering and allows for quicker water recovery. Water that traditionally would be lost due to evaporation and seepage no longer end up in tailing and a larger proportion of water can be recovered within minutes versus hours or days.
The leading suppliers in the flotation space are releasing new solutions that they say help a plant improve recovery and throughput while using less energy, manpower and …
