| titleOfInvention | Method of treating arsenic and compound containing arsenic |
| abstract | An object of the present invention is to provide a method of treating arsenic that can be treated to a stable form suitable for long-term storage and preservation, which is contained in copper ore containing arsenic. SOLUTION: A roasting step of roasting a copper ore containing arsenic in a non-oxidizing atmosphere and separating it into chalcopyrite and a volatile substance containing arsenic sulfide, and volatiles obtained in the roasting step Heat-treating in a non-oxidizing atmosphere to melt arsenic sulfide in the volatiles, pulverizing the pulverized volatiles after the thermal-treating, and heating and remelting the volatiles after the pulverizing. And a re-melting step. [Selected figure] Figure 1 |
