Flotation Machines in BrazilColumns perform the cleaning stage in a large sulfide copper concentrator, following rougher flotation in tank cells. Scavenger of the cleaner tailings is performed in tank cells at this plant. Other ores that are concentrated in flotation columns include graphite, talc, leadzinc sulfide, and a zinc hydrometallurgical residue for silver recovery.

1 Froth Flotation – Fundamental Principlesno flotation can occur. Contact between particles and bubbles can be accomplished in a flotation cell such as the one shown schematically in Figure 5. Figure 5: Simplified schematic of a conventional flotation cell. The rotor draws slurry through the stator and expels it to the sides, creating a suction that draws air down the shaft of the stator.
Column FlotationCOLUMN FLOTATION. ABSTRACT. Industrial appliion of column flotation began in earnest in the early 1980's, and is now accepted as a conventional appliion. For example, most of the world's major copper producers use column flotation as the final stage of cleaning.

Effect of Desliming on Flotation Response of Kansanshi ...The Kansanshi mixed copper sulfideoxide ore contains significant proportions of fine material manifesting in a variety of processing challenges. This paper presents the work which was carried out to evaluate the efficacy of desliming in improving the flotation response of the ore. Two modes of desliming were investigated, namely; sieving and elutriation after which the deslimed material was ...

Column Flotation Development for Copper Scavenging in Inco ...01/01/1991 · Testwork in pilotscale columns ( m, m and m in diameter) was used to develop a model of the copper scavenging system. This data was then used to simulate the performance of plantscale equipment. The relationships thus established were confirmed by a series of plant tests in a m diameter column.
INVESTIGATING THE POTENTIAL OF ...A number of tests were conducted on variety of copper sulphide ore samples. Fresh feed samples were ground in a rod mill to coarse size distributions, while plant samples were only screened to remove excessively coarse material. For each set of tests, a conventional rougher flotation test was conducted using a Denver laboratory flotation cell.
RECOVERY OF VALUES FROM A PORPHORY COPPER TAILINGS STREAMobtained using this novel flotation device in both laboratory and pilotscale trials showed that good recovery of previously lost sulfide values up to 850 m diameter could be achieved. Similarly, for ultrafine particles, a highintensity cavitationbased column cell was tested. This technology, which utilizes high
