Direct flotation is a process used in mineral processing technology to separate minerals from gangue by taking advantage of differences in their hydrophobicity. It is used in conjunction with other methods such as froth flotation and gravity separation to achieve the most efficient results.

Direct flotation is used to separate two minerals or particles of different densities by causing one of the particles to bind with the hydrophobic surface of a collector. This collector is then drawn to the surface of the particles and the two particles become attached to one another. The hydrophobic surface of the collector has a lower density than the two particles and so causes them to float together.

The process of direct flotation begins by mixing the two particles together and adding a collector. As the collector binds to the particles they become hydrophobic and begin to float. The particles are then skimmed off the top of the mixture and then separated by size.

The direct flotation process has been used to separate many different types of minerals including coal, iron ore, kaolinite, sulfur, and others. It can also be used to separate different classes of particles of the same mineral. It is often used as a pre-treatment step prior to other concentration methods such as froth flotation.

The direct flotation process is relatively simple and straightforward. It is also relatively inexpensive, making it a popular choice for mineral processing operations. The process is also very efficient and can yield high concentration ratios of up to 90%. It is also quite reliable, making it an excellent choice for many mineral processing operations.
