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 (Washability) Test, Coal Analysis, …
Float-sink tests are done on samples of coal from beds that will likely need washing (beneficiation, preparation) to remove sulfur or ash (rock and mineral matter) from the coal to meet the desired specifications of the end user.The float-sink analysis determines how much coal can be separated from rock and minerals in fluids of different densities.

Sink and Float Separation Process
Sink and Float PROCESS History and Development. For many years there have been effected in laboratory work separations of ore particles of different specific gravities through immersion of the mixed particles in a medium of a true heavy liquid with a specific gravity intermediate between the specific gravities of the heavy and light particles to be separated.
Coal Beneficiation Technology for Coking & Non-Coking Coal ...
clean coal in these washeries during 1989-90 was 12 million tonne and it is expected to go up to 37 million, tonne during 2015-16. Planning Commission has taken the decision that non-coking coal meant for Thermal Power Plants situated far away from feeding coalfield, should be beneficiated. Coal Washing is …
Using float–sink data in simple equations to …
In coal preparation, float–sink tests are widely used to estimate the amenability of coal towards gravity concentration and the performance of the coal-washing equipment. These tests are time-consuming and cumbersome, hence the float–sink tests are often carried out only at limited relative density levels.
Washability - an overview | ScienceDirect Topics
From the float and sink data of the two size fractions, 75–25 mm and 25–0.5 mm of a raw coal sample, washability curves are drawn as in Fig. 7.21.From the curves, the results are read and recorded in Table 7.7 where it was found that the yield of clean coal was maximum when the specific gravity cuts of the two fractions are same, and also the direct ash of both is the same.
