[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.
