Float-Sink (Washability) Test, Coal Analysis, Kentucky
In washability tests, coal samples are separated into float and sink fractions in liquids of increasing density. If a coal sample will be sent to a preparation plant that uses a fixed density for separating coal from rock and minerals, then a single float-sink test may be
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.

International Journal of Coal Preparation and Utilization
In Australia, coal washability analysis, which is used to obtain the cumulative yield—ash % relationship—has traditionally been generated using the float-sink method AS4156.1-1994 [1 AS 4156.1, Coal Preparation, Part 1: Higher Rank Coal–Float Sink Testing, Australian Standards ( 1994). [Google Scholar]].This technique relies on heavy organic liquids to fractionate coal and mineral
Float and Sink Analysis of Wet Coal ACARP
Float and sink analysis is traditionally done on air-dry samples. Commercial coal preparation, however, is carried out on wet coal. The density of an air-dry particle, in a float and sink liquid, is different from the density of a water saturated particle in a washery dense medium.
Float-Sink and Washability Testing Energy SGS
Washability characteristics are determined from float/sink analysis of core samples, as mined samples, or from preparation plant feed samples. During the test, your sample is characterized and quantified as low-density clean coal, high-density reject or intermediate-density middlings.

Float-sink test. Coal plies and particles have different relative densities, determined by vitrinite content, rank, ash value/mineral content and porosity. Coal is usually washed by passing it over a bath of liquid of known density. This removes high-ash value particle and increases the saleability of the coal as well as its energy content per
