Abstract (en)
[origin: WO8809390A1] In a process and a device for implementing hot chemical processes, in particular for melting and/or reduction by melting of batches of metallurgical dust, ores and other meltable or melt-reducible materials, such as SiO2, MgO, TiO2, Ta2O5 or the corresponding metals, the batches of specified composition to be melted or reduced are pressed into ingots which are arranged and maintained in caverns of specific shape around a high-intensity radiation source.
Abstract (de)
In einem Verfahren und einer Vorrichtung zur Durchführung heißchemischer Prozesse, insbesondere einer Schmelze und/oder Schmelzreduktion von Gemengen aus Hüttenstäuben, Erzen und anderen schmelz- und/oder schmelzreduzierbaren Materialien, wie z.B. SiO2, MgO, TiO2, Ta2O5 oder den entsprechenden Metallen, werden die zu schmelzenden und/oder zu reduzierenden Gemenge definierter Zusammensetzung zu Blöcken gepreßt und diese unter Ausbildung und Aufrechterhaltung einer definierten Kavernengeometrie um eine Strahlungsquelle hoher Energiedichte angeordnet.
