Recovering liberated valuable minerals at a coarser size range from the cyclone underflow using a flash flotation cell reduces over grinding and therefore the amount of fines reporting to the cyclone overflow in a traditional flotation circuit. This means the overall flotationics for the ore may be improved and this may lead to an overall improvement in recovery, as has been seen at many
The distribution of bubble size Figure 6 shows that the majority of mechanical flotation cells operate in the range between 1.0mm and 1.5mm. In contrast, flotation columns have, in general, larger bubble sizes with a distribution between 2.0mm and 2.5mm.

Flotation column cells are flotation act as three phase settlers where particles move downwards in a hindered settling environment counter current to a flux of rising air bubbles that are generated by spargers located near the bottom of the cell. The sparger technology is an important design choice, and allows the user to optimize the performance based on the feed characteristics size

Theic behaviour was then modelled at a laboratory batch scale in order to determine the time scale up factor between laboratory batch flotation data and industrial size flotation. The time scale up factor observed for large sized cells, 160 m3, was found to be reasonably similar to those previously determined for self aerated mechanical cells, but of lower size, operating at
size distribution and head grade, however these are the output of upstream processes and are not controlled in the flotation circuit itself. Each of the flotation cell control parameters are discussed below. Reagent dosing rate . The selection of reagent type and dosing rate is critical to successful processing of a given ore. It offers a coarse control mechanism as it is difficult to
This gives in depth information on whether the flotation cells are generating an adequate bubble size range, which relates to adequate mixing. SAMPLING CAMPAIGN. The purpose of sampling campaigns is to gather in depth information from the process that is not available from the automation system or daily sampling. Before the campaign, it is important to review the circuit flowsheet, assess data
In Mineral Processing Design and Operations Second Edition, 2016. 18.5.1 Batch Flotation. The concentrate obtained from a batch flotation cell changes in character with time as the particles floating change in size, grade and quantity. In the same way, the concentrate from the last few cells in a continuous bank is different from that removed from the earlier cells.
