Process and vacuum sublimation furnace for treatment of ores |
| abstract |
In a process for the reduction of the content of sulphide impurities in a solid particulate sulphidic concentrate, material from a hopper (3) is supplied to a rotating hearth (8) and caused by rabble blades (10) to spiral towards the centre. Radiant heaters (11) cause impurities to be vapourised and these are drawn off through an outlet (12) connected to a vacuum creating device. Heat-treated material drops through holes (13) onto a water cooled stationary under hearth (14). A second set of rabble blades (15) moves material to the under hearth periphery and through valves (16) to storage hoppers (17). Other forms of heating furnace suitable for the process are described. <IMAGE> |
