Role Of Depresent In Forth Flotation Process

The importance of froth flotation process is that, it is easy to separate two sulphide ores present in a mixture (by adjusting the oil-water proportion or by using depressants). Also this process is significant because it allows for the economic extraction of metals from lower grade ores.

With the depleting reserves of high-grade iron ore in the world, froth flotation has become increasingly important to process intermediate- and low-grade iron ore in an attempt to meet the rapidly growing demand on the international market.

flotation tailings and can be readily recovered by flotation with different flotation reagents. When amyl xanthate is used, 85% of chalcopyrite can be recovered with a copper grade of 14.5% in a single-stage froth flotation. The chalcopyrite flotation concentrate can be sent back to chloride leaching circuits.

of the flotation cell. The recovery of the froth is accomplished by the natural mobility of the froth which causes it to flow over the weir and the recovery is sometimes assisted by mechanical paddles. Within this general macroscopic view of the flotation process as a whole, several distinct micro processes can be identified.

In the flotation process, there is one thing that plays a very important role in the whole process——flotation froth.So what’s the role of flotation froth in the flotation process?

During the flotation process, frothers help create the ideal hydrodynamic conditions (such as bubble size and gas holdup) required within the pulp in the flotation cell. They generate froth that is stable enough to hold collected minerals on top of the pulp, mobile enough for removal, and decays quickly to assist with downstream operations.

Depressants prevent certain type of particles from forming froth during froth floatation process. A common depressant used in the froth floatation of lead sulphide is sodium cyanide. When the ore containing ZnS and PbS is subjected to froth floatation process in the presence of NaCN, then only PbS forms the froth.

In the froth floatation process, the role of the depressants is to separate two sulphide ores by selectively preventing one ore from forming froth. For example, to separate two sulphide ores (ZnS and Pbs), NaCN is used as a depressant which selectively allows PbS to come with froth, but prevents ZnS from coming to froth.

First there are DEPRESSANTS, they are added to prevent the unwanted minerals from floating. Next comes the COLLECTORS this reagent is used to gather the minerals. This reagent will attach itself to an air bubble while it is also attached to the mineral, as the air bubble rises to the surface of the slurry it will lift the mineral away from the waste.

Froth flotation is considered to be the most widely used method for ore beneficiation. In ore beneficiation, flotation is a process in which valuable minerals are separated from worthless material or other valuable minerals by inducing them to gather in and on the surface of a froth layer.

Figure 1: The flotation system includes many interrelated components, and changes in one area will produce compensating effects in other areas (Klimpel, 1995) Froth flotation is a good example of an engineering “system”, in that the various important parameters are highly inter-related, as shown in Figure 1.
