However, pyrite waste is potentially reusable. Therefore, this study aimed to evaluate possible ways of waste and effluent valorization that are generated during the processing of coal mining pyrite (R1). Raw R1 were subjected to two consecutive leaching processes in distilled water (20 g/L, 70 °C) under mechanical stirring for 40 min.

The catalytic activity of pyrite ore from coal mining was studied in the direct liquefaction process of high volatile bituminous coal from the south of Brazil. The process consisted of mixing pulverized coal with tetralin in the presence of catalyst. It was possible to obtain fractions of preasphaltenes, asphaltenes, and oils.

Pyrite seldom forms in fresh-water environments. The formation of pyrite crystals depends mainly on the iron content of the sediment. The process of pyrite formation in sediments results from the action of bacteria, which reduce sulphate ions (dissolved in the pore water) to sulphide. If there is iron present, iron sulphide crystals begin to grow.

Pyrite is an iron sulphide mineral, meaning it is made up of iron and sulphide. According to research, extracting this gold might be more energy-efficient than existing gold-mining methods. It aids in the clarification of mental processes, the reawakening of ideas, and the making of decisions. It functions as an excellent energy barrier

This process was responsible for a number of physical-chemical changes in the liquid, all of which contributed to the formation of the As- and Au-rich overgrowths in pyrite: (1) removal of H 2 O into the vapor phase, inducing saturation of dissolved metals in the remaining liquid; (2) an increase in pH due to partition of H 2 S and CO 2 into
