What is pyrite used for-What is pyrite used for?

Application I
CN201,410,490,074.8 reported a method for extracting gold from pyrite.Through pretreatment of pyrite,the gold contained in pyrite is exposed from the crystal lattice of pyrite,thus ensuring that gold can react with hydrochloric acid and calcium hypochlorite in the leaching step,and then dissolve in the easy solution,and then add alkaline anion resin solution to the solution,The gold and platinum in pyrite are adsorbed in the alkaline anion resin solution,thus reaching the state of enrichment,making the concentration of gold more and more large,avoiding the technical problem of extracting gold at low concentration,thus improving the extraction rate of gold from pyrite.Especially in the separation step,thiourea is used to analyze gold and reductant is added to reduce gold,so that gold and platinum are separated,It further improves the gold extraction rate and reduces the gold extraction cost.
Application II
CN202010153618.7 discloses a method for degradation of organic pollutants by pyrite catalyzed hydrogen persulfate,which belongs to the technical field of wastewater treatment.The particle size obtained by ball milling is 0.2μ~fourμM pyrite powder sample successfully catalyzes persulfate to generate sulfate radical with strong oxidation ability,and effectively treats wastewater containing organic dyes,antibiotics and other organic substances in the pH range of 2.7~12.1.The invention has the advantages that:the hydrogen persulfate in the invention is not only chemically stable,but also can play a role in a wide pH range;Pyrite is not only rich in source and low in price,but also non-toxic and harmless.Therefore,pyrite catalyzed persulfate has great practical application value in the treatment of organic wastewater discharged from chemical plants,printing and dyeing plants,pharmaceutical plants,etc.
