The present work investigates a comparative study between mechanical and ImhoflotTM cells on a mini-pilot scale and the applicability of one self-aspirated H-16 cell (hybrid ImhoflotTM cell) on an industrial scale on-site. The VM-04 cell (vertical feed to the separator vessel with 400 mm diameter) was fabricated, developed, and examined. The …

Although a bank is the simplest interconnection of cells in a circuit, i.e., the tails of one cell is the feed to the next cell down the bank, how to operate each flotation cell in a way that the whole bank performance is optimized remains a challenge.Significant efforts have been made towards understanding the effect of operating variables on the …

"The single most important method used for the recovery and upgrading of sulfide ores", that's how G. J. Jameson described the froth flotation process in 1992. And it's true: this process, used in several processing industries, is able to selectively separate hydrophobic from hydrophilic materials, by taking advantage of the different categories …

Fig. 1 shows the circuit in which a copper ore feed is upgraded first in a rougher bank, consisting of five mechanically agitated flotation cells, each with a volume of 127.4 m 3. The froth product is further upgraded in the coarse cleaner bank, with its concentrate being reground and subjected to column flotation to obtain a copper …

The froth flotation process typically involves a series of multiple flotation cells arranged in a sequential manner. This configuration allows for a step-wise separation of valuable minerals from the ore, with each cell playing a specific role in the overall process [].The use of multiple cells in series enhances the efficiency of the flotation process by optimizing …
