· Coal and coal preparation products are also potential sources of rareearth elements. REEs are a group of elements (shown in purple on the periodic table below) unknown to most people. They include the lanthanide series elements (cerium through lutetium), yttrium, and scandium. Although relatively unheard of, rare earth elements are very important in our modern technological world,

Pyrite is usually found associated with other sulfides or oxides in quartz veins, sedimentary rock, and metamorphic rock, as well as in coal beds and as a replacement mineral in fossils, but has also been identified in the sclerites of scalyfoot gastropods. Despite being nicknamed fool''s gold, pyrite is sometimes found in association with small quantities of gold.

Coal is a combustible black or brownishblack sedimentary rock, formed as rock strata called coal is mostly carbon with variable amounts of other elements; chiefly hydrogen, sulfur, oxygen, and nitrogen. Coal is formed when dead plant matter decays into peat and is converted into coal by the heat and pressure of deep burial over millions of years.
