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.

1.1 This test method describes procedures for determining the washability characteristics of coarse-coal fractions and fine-coal fractions. Each sample being tested can have more than one coarse-coal size fraction and more than one fine-coal 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 ...
Coal washing represents the most important step of coal preparation. The raw run-of-mine 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 .

Dec 19, 2012· A brief video demonstrating the process of a fine and coarse coal float/sink (AS4156.1)
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 .
ASTM's coal and gas standards are instrumental in the testing and chemical analysis of coal, coke, natural gas and other gaseous fuels, as well as the combustion residues of coal and coke. The materials specifically covered by these standards can be in the form of lump coke, pulverized coal, bituminous coal, coke and coal ash, reformed gas, and ...

The "Index of washability" (IW) and "Near gravity material Index" (NGMI) were used as parameters to express the ease of washability. Run of Mine coal is crushed to four different sizes as ...
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.
Oct 22, 2016· The results of float-and-sink 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.

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 Sole-Heated Oven.
Sep 05, 2017· The existing Australian Standard for float and sink analysis of coal is likely to be phased out over the next five years because of its reliance on toxic organic liquids. Thus, the Australian coal industry needs to urgently find a suitable alternative, allowing enough time to establish a new approach with a new standard. It is possible that the industry in other countries will follow this lead.
The behavior of raw coal in a wet washer can be predicted from laboratory simulation tests known as float and sink test and washability test. A sample of the coal to be cleaned is immersed in a liquid of specific gravity 1.6 which may be either CCl 4 or an aqueous solution of CaCl 2. Dirt will sink and can be removed and weighed.
