Improving the Properties of Mined Coal. Kentucky coal is improved by the partial removal of the impurities—sulfur and ash. The cleaning process to remove impurities from the coal is often called beneficiation, coal preparation, or coal washing.. In general, coal cleaning is accomplished by separating and removing inorganic impurities from organic coal particles.

The first washing methods were imported from Europe, The "Chance" washer, in which the density differences between coal and mineral matter was exploited to clean raw coal was introduced in 1918. The Chance washer utilized sand and water as a medium. Today, the "heavymedia" process using magnetite is standard for coarse coal cleaning.
