Sep 17, 2019 Coal type is a specific geologic classification based on the general appearance of coal. Most coals have internal layering, called banding. Coal types, and subsets of types, called lithotypes, are based on the presence or absence of banding, and the brightness or dullness of individual bands. Coal lithotypes are further divided into microscopic ...
Different Types of Coal. It is important to be aware that coal can cover a variety of finished products of differing values and requiring different treatment.
