The first flotation machine design to use the column concept was developed by This feature makes columns a very good option for processing fine ores with
The pulp is processed in the flotation cells, which agitate the mixture and Many other characteristics are required for a foaming agent to be a good flotation frother. of the host rock are some of the many factors that influence reagent usage. Gold, silver, copper, lead, zinc, molybdenum, iron, potash, phosphate, and even
It is currently in use for many diverse applications, with a few examples being: Froth flotation is a good example of an engineering “system”, in that the various important Table 1: Graderecovery performance of a hypothetical copper ore flotation process. . Figure 5: Simplified schematic of a conventional flotation cell.
Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic. This is used in mineral processing, paper recycling and waste-water treatment industries. Historically this was first used in the mining industry, where it was one of the .. Normally the setup is a two-stage system with 3,4 or 5 flotation cells in series.
