PROCESS AND PLANT FOR THE TREATMENT OF MINERAL CONCENTRATE PARTICLES CONTAINING VALUABLE METALS. |
| abstract |
The present invention has to do with a process and a plant for the treatment of particles of mineral concentrate containing valuable metals and having at least components containing arsenic and sulfur. The process comprises a two-stage roasting process comprising a first roasting step (1) made in a first roasting reactor (16) and a second roasting step (3) made in a second roasting reactor (17). A gas mixture is formed from the first component (2) of process gas that is obtained from the first roasting step (1) and from the second component (4) of process gas that is obtained from the second Roasting step (3). The post combustion of the gas mixture is carried out in a post-combustion chamber (6). The post-combustion works with said first component (2) of sulfur-rich and reducing process gas and the second component (4) of process gas as oxidation gas for the purpose of decomposing SO3 in the gas mixture to reduce the content of SO3. The risk of accumulation and corrosion formation in the afterburner chamber and subsequent steps is reduced. Finally, the outlet gas (7) is exposed to cooling steps with subsequent gas and dust removal. |
