Razdvajanje pirita i arsenopirita oksidiranjem sirovina tetrahedrita pod tlakom

One of the ways to process tetrahedrite concentrate is use hydrometallurgical method. A promising way seems to be pressure leaching which means that leaching at increased temperature. In the presented work the effects of temperature, time, concentration of the leaching solution and density of the slurry on the efficiency of pyrite and arsenopyrite decomposition by oxidative pressure leaching have been studied. At conditions chosen and studied, the degree of arsenopyrite decomposition was higher than it was in the case of pyrite.Jedan od načina obrade koncentrata tetrahedrita je hidromehanički način. Pokazuje se da ispiranje pod tlakom, tj. ispiranje uz povišenu temperaturu ima najviše izgleda da se i ubuduće upotrebljava. U ovom radu se proučavao utjecaj temperature, vremena, koncentracije otopine za ispiranje i gustoću mulja na učinkovitost razdvajanja pirita i arsenopirita pomoću oksidacije pri ispiranju pod tlakom. Pod odabranim i proučenim uvjetima stupanj razdvajanja arsenopirita je bio viši nego stupanj razdvajanja pirita
