| 5385601 | Process for converting aluminum dross to ladle flux for steel processing An indirect plasma-arc processor for aluminum dross is disclosed. The process involves melting aluminum dross in the presence of a flux in a furnace equipped with one or more arc-forming electrodes, wherein the arc is formed with a gas, such as argon. Mol... | 01/31/1995 |
| 4917725 | Process for treating electric furnace dust A process for treating electric furnace dust comprising mixing electric furnace dust and a reducing agent with a material for reducing the slag melting point, preheating the mixture, adding the preheated mixture to molten slag which is being subjected to ... | 04/17/1990 |
| 4889702 | Process for removing metallic constituents from dust obtained during the electrothermal production of yellow phosphorus Metallic constituents, especially heavy metal constituents are removed from dust electrostatically separated from a gas mixture consisting substantially of carbon monoxide and phosphorus in vapor form obtained during the electrothermal production of yello... | 12/26/1989 |
| 4889555 | Process of making binderless briquets from steelworks dusts To produce smeltable briquets, steel-works dusts containing more that 15% metallic iron are heated in an indirectly heated rotary kiln to a briquetting temperature in excess of 500° C. under an atmosphere which is inert to the metallic iron. The heated d... | 12/26/1989 |
