Froth flotation
Flotation processes are described in ancient Greek and Persian literature. During the late 19th century, the process basics were discovered through a slow evolutionary phase. During the first decade of the 20th century, a more rapid investigation of oils, froths, and agitation led to proven workplace applications, especially in Broken Hill, Australia, that brought the technological innovation kFlotation process in wastewater treatmentFlotation had its beginning in mineral (ore) processing and as such has been used for a long time in solid/solid Overview of flotation as a wastewater treatment technique

Flotation process is broadly divided into rougher, cleaner and scavenger stages, each using many (bank of) flotation cells : Concentrate from the rougher stage are further concentrated in the cleaner stage. Tailings from the rougher or cleaner stage are fed to the scavenger stage.Flotation cleaner, is really 'water dilution' cleaning. Too often the cleaner-recleaner slurry density is simply too high.

Enhancement of coal flotation using impact flow conditioning pulp
To improve the flotation efficiency, achieving the clean production of fine coal, a new method using impact flow conditioning pulp to enhance coal flotation was proposed. Furthermore, the flotation intensification mechanism using impact flow conditioning pulp was studied by SEM-EDS, adsorption measurements, contact angle The optimized flotation conditions were as follows: pulp concentration of 100 g/L, inflation rate of 0.25 m 3 / (m 2 min), collector (C4) dosage of 300 g/t, frother dosage of 500 g/t, and revolving speed of 2200 rpm. The ash content of clean coal was also reduced by adding a depressant.Optimization of Coal Washery Tailings by Flotation Process

Optimize flotation process of Mo–Bi sulfide ore for cleaner
As a result, the annual cost of flotation reagent alone was reduced by approximately USD 60407.0, displaying considerable economic benefits. Compared with the commonly used flotation process, the modified flotation process is an environment-friendly improvement for froth flotation plant to realize cleaner production and Froth flotation is a mineral processing technique that is popular when processing low-grade ores. It involves introducing chemically treated, finely ground ore in the form of a slurry into a flotation cell where the air is also added in the form of bubbles. The cell is agitated resulting in the air bubbles rising to the top and creating a froth, as Froth Washing in Flotation Encyclopedia MDPI

1. Introduction. One of the most unique separation techniques is considered to be flotation, which combines three phases: Gas phase, liquid phase, and solid phase (separately). Flotation has direct application to (or we can say that it originates from) mineral processing, which is called “froth flotation”.Natural graphite ores are usually upgraded by froth flotation. However, complex processes with multistage grinding and flotation are required to achieve decent liberation and separation of graphite and gangue minerals.

Enhancement of flaky graphite cleaning by ultrasonic treatment
Many scholars have explored the flotation process of oxidized coal and coal with a high ash content using ultrasonic treatment. Existing studies showed that, at the same dosage, a higher yield of clean coal and lower ash content in the clean coal can be attained by conducting ultrasonic treatment flotation [4–11].
