Froth flotation froth flotation is a common method to extract a certain type of mineral from ore while depressing the amount of undesired minerals in the extracted concentrate it is done by adding certain chemical reagents to selectively rendering the desired mineral hydrophobic in a flotation cell air bubbles then lifts the mineral read the rest
Froth flotation froth flotation is one of the most versatile and flexible of all mineral separation processes reasonable reagents were developed in the 1920s and played a major role in the spread of flotation throughout the world hydrocarbon chain length is from ethyl c2 propyl c3 butyl c4 amyl c5 to hexyl c6

Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic this is used in several processing industries historically this was first used in the mining industry where it was one of the great enabling technologies of the 20th century various flotation reagents are added to a mixture of ore and water
The theory behind chemical reagent behaviour in froth flotation has been studied extensively eg aplan 1980 fuerstenau 1976 fuerstenau 1962 and somasundaran 1980 and certainly important progress has been made unfortunately the nature of the flotation process with its complicated heterogeneous surface chemisty activity
Also called reagentizing conditioning is a critical step in potash froth flotation and also in many other industries that use froth flotation such as when liberating phosphates conditioning combines various reagents with the pulp in order to enhance the hydrophobic or hydrophilic nature of the materials ultimately improving separation

1 introduction flotation is known as froth flotation and it is a physicochemical reaction process flotation is the process which is based on the differences of the surface property of solid materials to separate useful minerals and gangue by means of the buoyancy of air bubbles from ore pulp by this method to improve the concentrate grade in the production process of flotation
Excessive slime will result in the decrease of concentrate grade affect the froth flotation of coarse grains consume flotation reagents and damage the aeration conditions the most common solution is to use a hydrocyclone for slurry desliming if the slurry is easy to float but also in the froth flotation before adding foaming agent alone
Apr 28 2006 this work was performed to determine the relationship between the reagents adsorbed on the solid particles froth structure and froth flotation performance the 53 m size fraction of a bituminous coal was used to perform froth flotation experiments
