Abstract:
A process and a plant for treating ore concentrate particles containing valuable metal and having at least arsenic and sulfur containing components. The process comprises a two-stage roasting process comprising a first roasting step and a second roasting step. A gas mixture is formed from the first process gas component obtained from the first roasting step and from the second process gas component obtained from the second roasting step. Post combustion of the gas mixture is made in a post combustion chamber that uses the sulphide rich first process gas component and the second process gas component as oxidizer gas in order to decompose SO3 in the gas mixture. The exit gas is exposed to subsequent gas cooling and dust removal steps.
