Washability and Distribution Behaviors of Trace Elements ...

Abstract: The float-sink test is a commonly used technology for the study of coal washability, which determines optimal separation density for coal washing based on the desired sulfur and ash yield of the cleaned coal. In this study, the float-sink test is adopted for a high-sulfur Late Permian

ANALYTICAL REPRESENTATION OF …

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. Usually, their plotting is conducted manually on graph paper, which is a very time-consuming and laborious procedure. This issue is arising, from ...
