froth flotation process powerpoint
Froth flotation is one of the most versatile and flexible of all mineral separation processes. Reasonable results are fairly easy to obtain but outstanding performance from a circuit requires constant attention and good understanding of the process and ore. Some of the variables that affect the operation and control of a flotation process are

froth-flotation process. Ground ore mixed with xanthates (salts esters of xanthic acid), dithiophosphates, or thionocarbamates. These make the ore surface hydrophobic. Ore then introduced into a water bath where air is bubbled through the suspension. Finely divided hydrophobic ore particles latch on to the air bubbles and travel to the surface

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 what allows the formation of air bubbles.

The principal ore of zinc used for its extraction is Zinc blend ( Z n S). As Zinc blend is a sulphide ore, the process used for its concentration is the Froth Floatation Method. The concentrated ore is then roasted in excess air at 1200 K to obtain zinc oxide ( Z n O). It is then reduced to Z n by coke at a temperature of 1673 K.

Flotation is a selective process and can be used to achieve specific separations from complex ores. For example, in poly-metal ores such as Pb-Zn- Cu, floatation allows separate extraction of Pb, Cu and Zn.
