REDUCTIVE METHOD FOR PRODUCTION OF METALLIC ELEMENTS SUCH AS CHROME USING A CRUCIBLE WITH A PERFORATED WALL |
摘要 |
The invention relates to a method for production of metals or metal alloys of high purity, in particular metallic chrome, whereby metallic elements are treated under pre-determined conditions of temperature and pressure. Said elements comprise non-metallic inclusions and a reducing agent such that the agent reacts with the inclusions. During the treatment, the elements (26) are arranged in a crucible (2) with a mouth (14) and a wall (4) having at least one opening (24). |
