What does froth flotation separate?
Froth flotation is an important concentration process that selectively separates hydrophobic valuable minerals from hydrophilic waste gangue. The minerals and metals (i.e., hydrophobic particles) attach to the air bubbles, which rise to the surface. The remaining material from the ore does not rise to the surface.
Which type of ores are concentrated by froth flotation process give examples?
Types of ores that can be concentrated by froth flotation method are sulphide ores. Examples are PbS (sulphide galena) and ZnS (zinc blende).
Which type of ore can be concentrated by froth flotation method give two examples for such ores?
Which type of ore is concentrated by froth floatation process?
Which ores can be purified by froth flotation process?
The ore which is purified by froth floatation process is- The process froth floatation is generally used for sulphide ores of copper, lead and zinc.
What are flotation kinetics?
Flotation kinetics relates directly to the effect of double layers on the rate of film thinning during bubble–particle contact.
Which ore is separated by froth flotation method?
We should know that this method of froth floatation is a method of mineral processing in which different minerals are separated according to our need. Such ores containing multiple metals such as lead, copper and zinc can be selectively extracted by using froth floatation.
Which ore is best concentrated by froth flotation?
galena ore
As the galena ore contains sulphide group, therefore galena is best concentrated by the froth flotation method.
Which ore can be concentrated by froth flotation?
. As the galena ore contains sulphide group, therefore galena is best concentrated by the froth flotation method.
Which type of ore is used in froth flotation method?
The development of froth flotation has improved the recovery of valuable minerals, such as copper- and lead-bearing minerals….Specific ore applications.
| Sulfide ores | ||
|---|---|---|
| Copper (see copper extraction) | Copper-Molybdenum | Lead-Zinc |
| Fluorite | Tungsten | Lithium |
| Tantalum | Tin | Coal |
Which ore is concentrated by froth flotation?
Why are sulphide ores concentrated by froth flotation?
Only sulphide ores are concentrated by the froth flotation process because pine oil selectively wets the sulphide ore and hence brings it to the froth. The sulphide ores preferably wetted by the oil and the gangue with the water.
