Flotation can be used in processing metallic ores (e.g. copper, lead, zinc, gold, silver) or non-metallic ores (e.g. day, phosphate, coal). The most widely used process in the world for extracting minerals, flotation also recovers several metals from a single ore body into two or more concentrated products.

Nov 01, 2019The froth flotation process is generally carried out at room temperature, sometimes heating the pulp appropriately is conducive to obtain a good separation effect. Specific temperature should be determined according to the specific circumstance. If the factory conditions allow, it is best to use waste heat and waste gas as far as possible.

Froth floatation process is used for the sulphide ores. In this method, wetting of the ore by an oil takes place. A strong current of air is blown through the suspension, producing a heavy froth or on the surface. The metal sulphide is wetted by the oil but the gangues is not and the sulphide-oil mixture is carried to the surface by films of oil The froth is skimmed off, the

Hint: Think about the name of the process, the term froth floatation defines what exactly happens in the process i.e. separation. You will arrive at the answer by inferring the implication of separation.
