Why is the froth flotation method only used for sulphide ores?
Jun 04, 2020 · Only sulphide ores are concentrated by froth flotation process because pine oil selectively wets the sulphide ore and hence brings it to the froth. This method is also used in waste recyling and stone industries.. this method also seperates hydrophobic substances from …
Why Only Sulphide Ore Is Concentrated By Froth Flotation ...
Only sulphide ore is concentrated by froth floatation method. This is because the sulphide particles present in the ore are preferentially wetted by the froth formed by the oil used in the process and rise to the surface where they are skimmed off. Why …
Assertion : Sulphide ores are concentrated by Froth ...
Assertion : Sulphide ores are concentrated by Froth Flotation method. Reason : Cresols stabilise the froth in Froth Flotation method. processes of isolation of elements
Why is it only sulphide ores are concentrated by froth ...
Froth floatation works by formation of froth which contains the ore, while the gangue remains in water. For this the oil (pine oil) used to make the froth should only have an affinity to the ore and not to the gangue. Sulphide ores have that property. Which means the pine oil wets the Sulphide ore but not the gangue.
Why is froth floatation method used for concentration of ...
Jun 02, 2019 · Only sulphide ores are concentrated by froth flotation process because pine oil selectively wets the sulphide ore and hence brings it to the froth. ... This method is usedfor that metals whose ore gets preferably wetted by the oil and the gangue by the water.
Sulfide Copper Ore Froth Flotation Plant With Of Two
Why Only Sulphide Ore Is Concentrated By Froth Flotation. Copper oxide ores have occasionally been treated via froth flotation via sulfidation of the oxide minerals with certain chemicals which react with the oxide mineral particles to produce a thin rime of sulfide usually chalcocite which can then be activated by the froth flotation plant ...
Froth Flotation Of Ores
The froth flotation method is widely used to treat various veins of gold and silver ores for the following reasons: (1) In most cases, the froth flotation process can enrich gold and silver in sulfide concentrate to the greatest extent and discard a large number of tailings, thus reducing the smelting cost.
Which type of ore is concentrated by froth floatat toppr.com
Sulphide ores are concentrated by froth - flotation process. Only sulphide ores are concentrated by this method because pine oil selectively wets the sulphide ore and hence brings it to the froth.

Froth flotation - Wikipedia
Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic.This is used in mineral processing, stone recycling and waste-water treatment industries. Historically this was first used in the mining industry, where it was one of the great enabling technologies of the 20th century.

Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic. ... The Elmores had formed a company known as the Ore Concentration ... the same lines in 1907, patented 1911, with some success on molybdenum ores. ... Froth flotation cells to concentrate copper and nickel sulfide minerals,... PDF A Review of the ...
What is the role of adsorption in froth floatation process ...
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, role of adsorption in froth floatation process can be understood as following processes. (i) Adsorption of pine oil on sulphide ore particles.
Sulphide ores of metals are usually concentrated by froth ...
The ore which can be attracted by the magnetic field can be concentrated by the process of magnetic separation. Among the ores mentioned in table 6.1, the ores of iron such as haematite (Fe 2 O 3), magnetite (Fe 3 O 4), siderite (FeCO 3), and iron pyrites (FeS 2) can be separated by the process of magnetic separation.

Also, the reactins can promote the formation of elemental sulfur, which promotes natural floatability causing difficulties in selective flotation, while the formation of a coating by the precipitation of insoluble metal hydroxides on sulfide minerals may interfere with the collector adsorption, thus impairing the flotation recovery.
