Froth flotation - Wikipedia
Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic.This is used in mineral processing, stone recycling and waste-water treatment industries. Historically this was first used in the mining industry, where it was one of the great enabling technologies of the 20th century.
An overview of reverse flotation process for coal ...
Again, during the same process when coal depressant (dextrin, 0.5 kg/t) was used, the ash content of LS-26 coal was reduced from 34.7% to 16.5% at a clean coal yield of 55%. Thus they were able to show that flotation of gangue minerals is very much improved by maintaining zero conditioning time in a coal reverse flotation process.

Study on Flotation Process of Coal Slime - …
1-8-2013 · The froth flotation process of coal slime was studied by the flotation experiments on the coal slime of Qian yingzi, Pan yidong and Qidong coal preparation plant. The influence of coal slime properties, collector dosage, ratio of collector and frother, and pulp density on the flotation effect were studied. The experimental result showed that the coal slime with rich fine and high ash fraction ...
Coal preparation plant - Wikipedia
A coal preparation plant (CPP; also known as a coal handling and preparation plant (CHPP), coal handling plant, prep plant, tipple or wash plant) is a facility that washes coal of soil and rock, crushes it into graded sized chunks (sorting), stockpiles grades preparing it for transport to market, and more often than not, also loads coal into rail cars, barges, or ships.
1 Froth Flotation – Fundamental Principles
