History of Sulphide ore flotation dates back to beginning of 20th century. Sulphide ores are major sources of base metals like Copper, Lead, Zinc, Nickel, Cobalt etc. Beneficiation of these is predominating through froth flotation technique. This technology has acclaimed importance as a versatile process for

Srdjan M. Bulatovic, in Handbook of Reagents, 2007. Processing characteristics of a massive . When using a conventional reagent scheme and flowsheet, only a few of these respond i.e. lime + NaCN + collector, giving extremely poor metallurgical results. The majority of these require a specific treatment to achieve satisfactory metallurgical ...

Answer Froth floatation process is especially suitable for sulphide ores. It is based on the difference in wetting characters of the ore and gangue with water and oil. Thus, both and Reason are correct and Reason is the correct explanation for Assertion.

The froth flotation technology of copper, lead and zinc sulfide ore is very rich. A certain copper, lead, zinc and sulfur ore in Tibet is used for partial mixed flotation process. It is mixed with medium ore for regrinding, and activated carbon is used as the agent for separation.

Descriptions of the use of a flotation process have been found in ancient Greek and Persian literature suggesting its antiquity. During the late 19th century, the process basics were discovered through a slow evolutionary phase. During the first decade of the 20th century, a more rapid investigation of oils, froths, and agitation led to proven work-place applications, especially at Broken Hill, Australia, that brought the technological innovation known as “froth flotation.” During the early 20th century, it dramatically revoluti…

The principle of froth flotation process is that sulphide ores are preferentially wetted by the pine oil, whereas the gangue particles are wetted by the water. In this process, a suspension of a powdered ore is made with water. In this process, a suspension of a powdered ore is made with water.

Best answer. In froth floatation process sulphide ore is shaken with pine oil and water, the ore particles are adsorbed on froth that floats and the gangue particles settle down in tank. Thus, roleof adsorption in froth floatation process can be understood as following …
