Data from your float-sink/washability tests provide you with the information that you need to ensure:
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.
Our float/sink analysis can be performed on samples ranging in size from bulk washability samples (over 1 ton) to bench-scale size samples. We conduct the tests over a range of densities (from 1.3 specific gravity up to 2.25 specific gravity) and a variety of sizes (from coarse to fine coal).
We also perform froth recovery testing on finer sizes. If your coal contains a high percentage of middlings, we can perform the crushing studies required to determine if you can obtain additional yield by liberating coal from the middlings through crushing.
We offer you a full range industry standard testing services for the coal and coke industry. Our float-sink/washability tests provide you with the information that you need to fully understand the characteristics of your coal, resulting in more growth from your coal operation.
SGS Minerals Services in the United States provides float-sink/washability tests at its laboratories in:
Our laboratories provide a range of washability services from single gravity quality checks through to full preparation plant performance studies. We efficiently process float-sink work in accordance with ASTM test methods to ensure you get a quick turn-around of your project.
