Flotation Froth - an overview | ScienceDirect Topics

However, this process is based upon density alone and should not be confused with the process of froth flotation. Thus, the process of froth flotation is not solely dependent upon the density of the material; it is also dependent upon its hydrophobic nature. For example, froth flotation is a technique commonly used in the mining industry.


Extraction of Copper

The copper ore is crushed into 250mm pieces, and carried through a tunnel on a 5 mile conveyor belt. This is done so that the segments will be smaller, and therefore more able to float in the next process. At this point the ore is made up of approximately 0.5% of copper . 2. Froth Flotation

Copper Mining and Extraction: Sulfide Ores

From the formula, it is clear that iron and sulfur have to be removed in order to produce copper. The roasting process: changes some of the CuFeS 2 to copper oxide; removes some of the sulfur as sulfur dioxide; This is done by heating the concentrated ore from froth flotation. It is heated to between 500 °C and 700 °C in air.


Copper extraction - Wikipedia

Supergene sulfide ores rich in native copper minerals are refractory to treatment with sulfuric acid leaching on all practicable time scales, and the dense metal particles do not react with froth flotation media. Typically, if native copper is a minor part of a supergene profile it will not be recovered and will report to the tailings.
