| titleOfInvention | Process and plant for the treatment of mineral concentrate particles containing valuable metal |
| abstract | A process for treating mineral concentrate particles that contain valuable metals and that have at least arsenic and sulfur-containing components, the process of which comprises: - roasting the concentrate particles in a first roasting step (1) that operates with a low potential of oxygen to desensitize the concentrate, - the residual gas leaving the first roasting step (1) is treated to separate the calcine and a first sulfur-rich process gas component (2), - roasting the calcine from the first step roasting in a second roasting step (3) that operates with an excess of oxygen, - the residual gas leaving the second roasting stage is treated to separate the calcine and a second process gas component (4), - post-combustion of the components of the process gas (2, 4) and - treat the process gas in the following steps of gas cooling and dust removal, characterized in that the process further comprises - forming a mixture of gases of the first process gas component (2) and the second process gas component (4) which is oxygen containing a hot oxidizing gas and - post-combustion of said gas mixture in a post-combustion chamber (6), said post-combustion operating with said first reducing and sulphurous process gas component (2) and said second process gas component (4) as oxidizing gas, to decompose SO3 in the gas mixture to reduce the SO3 content in the outlet gas (7 ) that exits the post-combustion chamber and to reduce the risk of accretion and corrosion formation in the post-combustion chamber and in subsequent steps, and - exposing the outlet gas (7) to the next steps of gas cooling and elimination of powder (8 to 11). |
