Flotation of minerals

Objective of the waterline it is a physical chemical process q allows the separation of sulfide minerals such as copper sulphide and molybdenum minerals from other q share most of the species original mineral, flotation is performed using the pulp from the grinding q has already incorporated the necessary reagents for the flotation, the pulp is placed in containers called flotation cells in which they grab a bubble air keeping the mixture under constant agitation for q particles enter the contact is intense.

To obtain the product of phase q reqiere flotation pulp is passing through several cycles sonde generate bubbles concentrate obtained eg copper concentrate q increases from values of 1% of the original rock up to 31% of total copper. The final concentrate is dried using appropriate equipment and taken to the smelting process.

Description of the flotation process.

Flotation is a process of concentration q is the selective separation of mineral species according to hidrofobizacion properties, in order to appreciate the froth flotation as a system of qimicas reactions and also as a technique maetalurgica is essential to understand because they practice this process.

Froth flotation as a means of treating pulp and minerals so sdales obtain a desired value of 0 in a concentration q be easy to handle for further processing. Under favorable conditions these coated particles bind to qimicamente q bubbling air through the pulp and thus float to the surface.

The flotation foaming or known as conventional float operated with a granulometry between 0.3 to 0.002 mm depending on the specific gravity of the species and its degree of liberation.

Collective flotation separation occurs several components into 2 groups of which the concentrate contains at least 2 or more components.

Selective flotation or differential separation is made of composites, q product contains no more than individual species.

Technology Flotation operation: consists of hydrophobic particles to selectively separate the hidrofilitas this is done in machines tuned q command.
One of the most important components in the float are the reactants.

Collectors: are organic compounds whose role is useful hidrofobizar particles, they will absorb on the surface of the particle selectively.
The action of the collector is full of great research mas q cualqiera another phase of the process, however, the actual mechanism of a collector adesiuon sige being a polemic.
