flotation in coal mining process

Froth flotation - Wikipedia

2019-11-29  Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic.This is used in mineral processing, 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.

Not only is the water pollution problem a serious one, but refuse storage and disposal in many areas is becoming limited and more difficult. Many breakers and washeries efficiently handle the coarser sizes, but waste the coal fines. This problem is assuming major importance du在911metallurgist上查看更多信息

COAL FLOTATION - Mineral Processing Metallurgy

Coal Flotation with non-ionic SurfactantsExperimental Materials and MethodsResults and DiscussionSummary and ConclusionsIn coal flotation, the most commonly used collectors are oily materials collectors such as diesel oil and kerosene. For higher rank coals, the reagent consumption in flotation is low because of the high natural hydrophobicity of the coal. However, for low-rank coals (containing a greater amount of oxygen), flotation performance with these oily collectors is poor and large amount of collectors are required in order to obtain acceptable coal recovery.Polyethoxylated nonyl phenols constitute a m

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.
