<p>A process for removing arsenic from solid furnace products, especially speisses, involves fluidising particulate solids in an oxygen-containing gas, in the presence of a sulphur source such as pyrites or elemental sulphur or employing SO2 as the fluidizing gas. The arsenic is fumed off as arsenic sulphide and is collected from the gas stream leaving the fluidised bed.</p> |
