Coal Mines - an overview ScienceDirect Topics
Coal preparation has been evolving for more than a century and the core of most of the process development work is in the area of separating the impurities from the coal, utilizing the physical difference in specific gravity between the coal and the rock impurities. An overview of the different coal cleaning systems is provided in Table IV.

Chapter 7 COAL - Pennsylvania State University
1998-6-25 Coal is an organic rock (as opposed to most other rocks in the earth's crust, such as clays and sandstone, which are inorganic); it contains mostly carbon (C), but it also has hydrogen (H), oxygen (O), sulfur (S) and nitrogen (N), as well as some inorganic constituents (minerals) and water (H2O).

Coal Particle - an overview ScienceDirect Topics
The technique of froth flotation, widely used to clean coal fractions below ∼0.5 mm in size, is based on selective attachment of the nonpolar surfaces of the organic components (coal particles) to air bubbles that rise through a suspension of fine coal and mineral solids in water. The coal particles are lifted with the bubbles and gather together in a froth at the water surface.

Best: Colorado’s last standing coal plant? VailDaily
2021-3-7 Two huge coal-burning plants, Comanche 1 and 2, were constructed near the steel plant, part of a spree of new coal plants across Colorado from 1965 to 1984. Now, those two units near Pueblo will grow cold beginning in 2022 and 2025. Most remarkable is how the Evraz steel mill will be powered.
