The figure also illustrates the often observed higher rate ability of some frother types on a given ore (e.g. in Figure X, the glycol ether type frothers such as DF-250 and DF- 1012 over MIBC), In this example, the relative rate selectivity of copper over gangue stays about the same with the different frothers.

Ore is mined and processed at an onsite flotation processing plant capable of treating up to 24 million tonnes per annum (Mtpa). The plant currently recovers copper, gold and silver into a saleable concentrate. The primary ore is crushed and ground using Semi-Autogenous Grinding and Ball mills to a final grain size of approximately 180 microns.

The Froth Flotation Process is about taking advantage of the natural hydrophobicity of liberated (well ground) minerals/metals and making/playing on making them hydrophobic (water-repel) individually to carefully separate them from one another and the slurry they are in. For this purpose we use chemicals/reagents: Frothers (MIBC) is …

With small amount of frother addition, it can improve oxidized coal flotation. The frother adsorbs onto the coal water interface and – provides the collector an anchor point [7]. In other words, a frother might work as an activator. However, once the frother addition exceeded a certain concentration, the frothers started to adsorb on
