Pyrite (Fool’s Gold) Properties, Formation, Occurrence and Uses

References. Pyrite, also known as “fool’s gold,” is a common iron sulfide mineral with the chemical formula FeS2. It forms in a variety of geological settings through several processes. Formation: Pyrite forms under reducing conditions, typically in environments with low oxygen levels, high sulfur content, and abundant iron.Coal is a hard black or brownish-black rock formed in rock strata called coal seams. It consists mainly of carbon but also contains hydrogen, sulphur, oxygen and nitrogen.

A review study of rare Earth, Cobalt, Lithium, and Manganese in Coal

So far, several rare earth-enriched coal deposits, such as deposits from the Russian Far East, China, and the United States, with a rare earth concentration ranging from 1000 s to almost 6000 ppm, have been identified (Fu et al., 2022).A study by the United States Geological Survey (USGS) estimated a minimum of 500 ppm rare earth elements The coal–oil–gold agglomeration process considers the preferential wetting of coal and gold particles. The method takes advantage of the greater hydrophobicity and oleophilicity of coal and gold compared to that the most gangue materials. Unlike the previous studies about coal–oil–gold agglomeration, this method uses a very small Utilization of coal-oil agglomerates to recover gold particles
