METHOD AND INSTALLATION FOR TREATMENT OF PARTICLES OF ORE CONCENTRATE CONTAINING VALUABLE METAL |
| abstract |
The present invention describes a method and an installation for treating ore concentrate particles containing valuable metal and having at least arsenic and sulfur-containing components. The method includes a two-stage firing process, including the first stage (1) firing, which is carried out in the first firing reactor (16), and the second stage (3) firing, which is carried out in the second firing reactor (17). The gas mixture is formed from the first component (2) of the process gas obtained in the first stage (1) of the calcination, and from the second component (4) of the process gas obtained in the second stage (3) of the calcination. The afterburning of the gas mixture is carried out in the afterburning chamber (6). Afterburning is carried out with said reducing first sulfide-rich process gas component (2) and with the second process gas component (4) as an oxidizing gas in order to decompose the SO in the gas mixture to reduce the SO content. The risk of formation of wall accretions and corrosion in the afterburning chamber and at subsequent stages is reduced. At the end, the exhaust gas (7) is fed to the subsequent stages (8-11) of gas cooling and dust removal. |
