Froth flotation process and its application
Froth flotation is one of the steps which is generally performed before roasting and it deals with the surface chemistry of liquids and of the minerals to be separated. This process requires a particular setup to be performed which contains different components. Surfactants play the most important role here.

Extraction of Zinc: Process, Ores, Diagram
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.

Fundamentals of froth flotation | ChemTexts
Froth flotation is a physicochemical process that is used to separate fine mineral particles from aqueous suspensions by selective attachment of some types of minerals to air bubbles. Froth flotation is the most important mineral processing technology for the production of valuable mineral concentrates from which metals and minerals are …
Extraction of Copper Through Froth Floatation Method
In this process, the property of ore minerals solubility is used. Froth floatation technique is used in primary that is un-weathered and secondary that is supergene sulphide ores to separate gangue from ore. Using simple gravity circuit, the mineral can be recovered from local copper with ore bodies that are rich in supergen copper.

Flotation of Chromite Ore
Deslimed chromite ore was floated at pH 1.5 to 5.5 using a long-chain fatty-acid collector and soluble fluoride ions as a silicate depressant. The Havens method was later modified slightly to permit flotation without preliminary desliming. This was done by preconditioning the pulp with fuel oil and fluoride ion.
