Oct 22, 2016· The results of floatandsink testing, presented in graphical form as washability curves, allow making a theoretical balance of coal processing products and establishing an optimal separation density to reach the maximum production of clean coal.
Coal washing represents the most important step of coal preparation. The raw runofmine coal requires selective qualitative and quantitative analysis for finding the most suitable operating conditions for cleaning coal to obtain the desired quality. Among these analyses, the washability test is .
The Physical Analysis tests determine the physical characteristics of the coal or coke, including: strength, size, washability, expansion and contraction. We are one of the few labs that can do CRI/CSR testing and Expansion Contraction by SoleHeated Oven.

Washability. The washability characteristics of a coal reserve are provided by obtaining liberation data on the raw coal sample. Liberation refers to the amount of physical breakage required to liberate coal from different other material densities. Low density material is clean coal .
Prairie''s coal quality and coal washability test work program is focused on determining potential product quality, yields and pricing in order to facilitate future marketing discussions with potential offtakers and endusers and to support the Scoping Study for the Project. The program is being directed
This test method describes procedures for determining the washability characteristics of coarsecoal fractions and finecoal fractions. Each sample being tested can have more than one coarsecoal size fraction and more than one finecoal size fraction (see Annex A1).Each such size fraction has an upper size limit and a lower size limit, neither of which overlaps with the next larger nor ...

The Australian Coal industry needs to find an alternative to the heavy organic liquids used to produce its coal washability analyses. Indeed, the existing Australian Standard for the Float and Sink analysis of coal is likely to be phased out over the next five years, and thus the matter needs to be urgently addressed to allow time to establish a new approach, with a new standard.
