Coal Washability by Release Analysis (2 replies)

Sudhirkumar 1 year ago

I am working on coal washability by release analysis using froth flotation technique. I want to know the particle size range at which to perform for this case, also want to know how much pH is important for this analysis.

Have you looked through some of the prior technical literature on this topic?

There are some additional factors we need to know to help you answer this question, e.g.

•What is the end goal of the analysis?

•What is the particle size distribution of the coal in the flotation size fraction?

•Some details of the coal: Rank of coal, impurities associated with the coal?

•pH dependence can be more or less depending on the particular coal.

Conducting release analysis by lab scale froth flotation machine is an established method.

As regards particle size range for a particular coal sample you can carry out the release analysis test for a size range of 250 microns to 5 microns like that and find out the optimum recovery or grade of the product.

Since you are likely to do the test works in the lab it is suggested to do the test work with treaded water having pH around 6-7
