Sažetak
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.
