La marcasite è un minerale solfuro di ferro da giallo a giallo argenteo con una composizione chimica di FeS 2 Si forma per precipitazione da acque acide in ambienti superficiali o vicini alla superficie La marcasite si trova comunemente in sedimenti rocce sedimentarie e depositi idrotermali in molte parti del mondo La marcasite è stata storicamente utilizzata come fonte di zolfo
Separation techniques mineral processing Flotation Flotation is a gravity separation process which exploits differences in the surface properties of particles Gas bubbles are generated in a liquid and become attached to solid particles or immiscible liquid droplets causing the particles or droplets to rise to the surface This is used to separate mixtures of solid solid particles and

The Wet Shaking Table separator is the oldest mineral processing method used to determine the maximum gravity recovery and it is used to separate the samples into light and heavy mineral fractions provided that there is a marked difference in the density of the minerals Due to its low capacity a few kilograms the shaking table is typically used as a Cleaner for final upgrading
Marcasite whose name is derived from the Arabic word for pyrite is a common and an attractive mineral The two minerals marcasite and pyrite are often confused due to their similar characteristics Marcasite is a polymorph of pyrite which means that it has the same chemistry as pyrite but a different structure and therefore different symmetry and crystal shapes The marcasite
