Flotation of Nickel-Copper Sulphide Ore: Optimisation …
Abstract-Froth flotation is widely used for concentration of base metal sulphide minerals in complex ores. One of the major challenges faced by flotation of these ores is the ever varying grade and mineralogy. This therefore calls for a continual characterisation and optimisation of flotation parameters such that concentrator performance as a
Froth Flotation Principles
The adaptation of flotation to the treatment of sulphide ores was a major step in the advancement of concentration technique.

Sulfide Ore
Copper sulfide ores must be concentrated before they can be economically transported and smelted. The universal technique for this concentration is froth flotation of finely ground ore. Froth flotation entails attaching fine Cu-sulfide mineral particles to bubbles and floating them out of a water–ore mixture.

Purification of Sulphide ore by froth floatation method. →. This method employs a mixture of water and pine oil which is made to froth in a tank to separate sulphide ores. The differences in the wetting properties of the ore and gangue particles separate them. A mixture of water, pine oil, detergent, and powdered ore is first taken in a tank.
Froth floatation process used for the concentration of sulphide ore:
Froth flotation is a process for selectively separating hydrophobic materials from hydrophobic. In some cases, for example, sulphides ores of copper, zinc and lead concentration is brought by this method.In this method, the advantage is taken of the preferential wetting of the ore by an oil.The finely ground ore is taken in a tank …
CHAPTER-9 FROTH FLOTATION AND ITS APPLICATION …
The flotation method of concentration, used extensively for other metal ores, has only recently been utilized for hematite iron ores. It can be applied as either the sole concentration process or as a final concentration stage to ensure a high-grade product. In the flotation process, air is bubbled through a suspension of fine iron ore in water
Froth flotation method is used for the concentration of
oxide ores. Froth floatation is based on the principle of the difference in the wetting properties of the ore and gangue particles with the water and oil. This method is used for those metals whose ore gets preferably wet by the oil and the gangue by the water. The sulphide ores get preferably wet by the oil and the gangue with the water.
Froth flotation is a process of
Froth flotation is a process of concentration. Froth floatation process is suitable for sulphide ores It is based on the difference in wetting properties of the ore and gangue with water and oil. This method is used for the concentration of F e C r 2 O 4.
Concentration of Ores: Hydraulic Washing, Froth Flotation …
Froth Flotation Process. Another method of concentration of ores is the Froth Flotation Method. This is the process for concentration of primarily sulphide ores. It has the advantage over gravity separation because it can collect even the extremely fine particles of minerals. The process uses the difference in the wetting characteristics of ...
Concentration of Ores
Explanation: Froth floatation is generally used for sulphide ores. It is based on the fact that sulphide ores are preferentially wetted by oils while that of the gangue is wetted by water. To a suspension of the crushed ore in water, collectors are added to enhance the non-wettability of the ore particles.
