Green and efficient comprehensive utilization of pyrite
1. Introduction. Pyrite concentrates, which contain rich pyrite (FeS 2), are solid wastes or byproducts in nonferrous metal production processes, such as copper, lead, zinc, and coal treatment.Pyrite has been the mineral resource for sulfuric acid production in China,,, .However, the pyrite concentrate produced by polymetallic sulfide mines has a high content of impurity elements, and the

Processing a bulk pyrite concentrate by flotation reagents
1992-3-1 A bulk auriferous pyrite concentrate from the Olympias plant in Chalkidiki (Greece), was the sample examined, having a size range of -75 + 45 #m; with a concentration of 11.8 % As, 40.5 % Fe, 26 ppm Au, and < 1% of Pb and Zn. The x-ray diagram showed that the concentrate mainly contained pyrite, arsenopyrite and some quartz.

2021-10-28 Pyrite is a polymorph of marcasite, which means that it has the same chemistry, FeS2, as marcasite; but a different structure and therefore different symmetry and crystal shapes. Pyrite is difficult to distinguish from marcasite when a lack of clear indicators exists. Pyrite's structure is analogous to galena 's structure with a formula of PbS.
