A 2 m diameter REFLUX™ Flotation Cell was fed at roughly 210 m 3 /h, equivalent to a flux of 1.9 cm/s, about twice the maximum rate used in conventional flotation cells. The coal feed slurry had 59–64 wt% head ash and nominal size range −0.100 mm (Sauter mean size 0.004 mm).
The cyclone overflow from each ball mill goes to a Pulp Distributor which distributes the pulp to two or more parallel banks of Flotation Cells. These distributors are designed so that one or more flotation banks can be shut down for maintenance or inspection and still maintain equal distribution of feed to the remaining banks.
Furthermore, natural gold grains are easily inhibited by Ca 2+, when there is a certain amount of lime in the pulp, Ca 2+ reacts with the CO 2 in the air entering the pulp to produce CaCO 3 precipitation, which inhibits the flotation of natural gold grains. Lime in flotation operations, usually used in the ball mill feed belt with lime powder ...

The Inspiration Copper Co. uses flotation as the prime process, and its 800 tons per section is treated by 24 roughing-cells and 4 cleaners. In this case the cells are run in series, the primary cells treating the original feed and the secondary cells re-treating only the slime from the primary tailing after the sand has been removed.
Lime addition to the mill also provides for good mixing of lime with the incoming ore. 2. Rougher flotation – Lime is added after primary (typically SAG) and secondary (ball) milling, usually in a conditioning tank, to ensure optimal pH control in the subsequent rougher flotation process. 3.
