A considerable difference exists between the flotation separation of artificial minerals and real low-grade ores processing where selectivity would be the main issue. Nanobubble-assisted (NB) flotation investigations have been mostly examined with pure materials and a narrow particle size range, less on complex sulfide ores.
However, the mechanisms of flotation selectivity for plastics in this flotation process and an effective separation of plastics still remain to be realized (Shen et al., 1999). In the present paper, the floatability of seven plastics in the presence of methyl cellulose (MC) and separation of plastics mixtures are investigated.
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 …

Flotation is the most widely used beneficiation method for fine materials, and almost all ores can be separated by flotation. Another important application is to reduce ash in fine coal and to remove fine pyrite from coal. The flotation machine is mechanical equipment for realizing the froth flotation process and separating target minerals from ore.
Flotation is a widely employed method in mineral processing and beneficiation for effectively separating mineral particles.
The exact mineral processing application, the ore's properties, and the desired separation efficiency all influence the type of flotation machine that is used. To get the greatest results from the flotation process, various machines may be utilized at various stages. 1.2, FWhat are the applications of flotation machines in the mining industry?
