selection or reverse flotation

An overview of reverse flotation process for coal ...

2015-1-10  Reverse flotation involves the flotation of ash forming minerals which means that the collectors used should be such that they make the mineral matter hydrophobic in nature. Some of the most common minerals found in coal are quartz, clay minerals (like kaolinite, illite etc.), feldspar, carbonates such as calcite, siderite and dolomite, and sulphide minerals such as pyrite.

In reverse flotation, proper reagents induce the pay minerals to become hydrophobic (water repelling) and the waste minerals to become hydrophilic (water attracting). Aeration is added through spargers at the bottom of the flotation cell. The bubbles attract and then float the waste minerals, leaving the pay minerals in the underflow.

2021-6-6  Flotation can be useful, however depends upon the gangue minerals. For example, if sulphide minerals are reasonably abundant, if not dominant (cf. the Renison operation in Tasmania - cassiterite in pyrrhotite) so-called reverse flotation i.e. flotation of the sulphide minerals would be used.

2013-7-18  Fundamentally important for the selection of a concentration method is the mineralogy of iron bearing minerals and gangue minerals presented to the feed to the concentration unit operation. For instance, the presence of liberated quartz as the major gangue mineral for a pellet feed size stream generally indicates that flotation will be the best selection for the concentration of that stream.
