Flotation may also prove to be the more economical process for an ore containing such minerals as stibnite, copper-bearing sulphides, tellurides, etc., which require roasting before cyanidation, since it reduces the tonnage passing through the furnace to a fraction of the original feed with considerable reduction of working costs in …

Column flotation cells, like mechanical cells, are used to perform mineral separations.Column cells do not use mechanical agitation (impellers). Instead, mixing is achieved by the turbulence provided by the rising bubbles.

A better solution may be to use a specially-designed flotation cell known tentatively as second-order flotation (SOF) cell. In this process, microbubbles are generated in a static mixer under highly turbulent conditions. A stream of CST is injected into the mixer so that bubble-particle attachment occurs under conditions of high-kinetic …

A high frother concentration produces an excessive amount of froth in the flotation cell. This increases the froth overflow and flotation rate, but, unfortunately it also decreases the concentrate grade. Collector concentration has a significant effect (either linear or non-linear) on all three quantitative response variables.

In fresh water, the oxidation of pyrite at alkaline pH inhibits the copper activation on pyrite surfaces and the depression of pyrite in copper ore flotation is normally not a problem (Li et al., 2012). However, saline water facilitates pyrite activation by copper ions and therefore increases pyrite recovery in copper flotation (Mu and Peng ...

The rougher flotation behavior of a sulfidized copper ore was studied by a series of batch flotation experiments. Response surface modeling based on central composite design was applied to optimize and evaluate the effects of collector, depressant and frother dosages, solution pH and agitation rate on the copper recovery.

Flotation Column Cells can only 'carry' or recovery so much froth/concentrate for any given diameter. Unlike a mechanical cell on which you can just turn-on more air to recover more metal, column cells with not respond that way. A column cell can only carry so much froth to the concentrate launder. Their concentrate production is ...

The full-scale separations were also compared with flotation results from a laboratory-scale 3.5 L mechanical flotation cell (FL Essa model FTM101). The feed for the mechanical cell tests had previously been conditioned with collector on-site (prior to sample collection), and thus no additional collector was added prior to the lab-scale test.
