Float-Sink and Washability Testing SGS

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.
