The Froth Flotation Process is about taking advantage of the natural hydrophobicity of liberated (well ground) minerals/metals and making/playing on making them hydrophobic (water-repel) individually to carefully separate them from one another and the slurry they are in. For this purpose we use chemicals/reagents: Frothers (MIBC) is what allows ...

A porphyry-type copper ore from Chuquicamata Mine, Chile, (assaying about 1% Cu), was subjected to a set of three flotation tests. In each test, approximately 1 kg of the ore sample was wet-ground in a laboratory ball mill at 66% solids. Lime and …
Froth flotation is an important concentration process that can be used to selectively separate hydrophobic materials from hydrophilic waste gangue. In a more simple context, froth flotation is one of the most popular operational processes for mineral beneficiation. In ore/mineral beneficiation, froth flotation is a method by which commercially ...
Flotation Result. Using a Mark IV surface force apparatus, adsorption of dodecylamine hydrochloride on mica has been studied at pH 5.7 in the presence and absence of octanol. With amine alone, the repulsive forces between mica surfaces are reduced due to charge neutralization and attractive hydrophobic force; however, the latter is of ...

The ground ore is mixed with water to form slurry which chemical reagents are added, and then aerated to produce bubbles. Using the principle that the hydrophobic ore particles attach to the bubbles, the target ores are recovered. From this process, copper concentrates with 20-40 %-Cu is produced, which is sent to a smelting and refining plant ...
Particles can either be naturally hydrophobic, or the hydrophobicity can be induced by chemical treatments. Naturally hydrophobic materials include hydrocarbons, and non-polar solids such as elemental sulfur. Coal is a good example of a material that is typically naturally hydrophobic, because it is mostly composed of hydrocarbons.
