MICROWAVE IRRADIATION OF MINERAL ORES AND CONCENTRATES

An admixture of mineral ore or concentrate and particulate carbon is irradiated with microwave energy to produce metallic droplets and the droplets are collected. In a preferred form the apparatus includes a hopper (11) which feeds the admixture (12) to an inclined column (5) through which the mixtu...

Zusammenfassung:	An admixture of mineral ore or concentrate and particulate carbon is irradiated with microwave energy to produce metallic droplets and the droplets are collected. In a preferred form the apparatus includes a hopper (11) which feeds the admixture (12) to an inclined column (5) through which the mixture passes and is radiated with microwave energy. A suitable liquid metal collector (6) is disposed at an output (20) of the column. Un mélange de minerai ou de concentré minéral et de carbone particulaire est irradié avec une énergie à micro-ondes afin de produire des gouttelettes métalliques que l'on récupère. Dans un mode de réalisation préféré, l'appareil comporte une trémie (11) ammenant le mélange (12) jusqu'à une colonne inclinée (5) à travers laquelle passe le mélange, lequel est irradié avec de l'énergie à micro-ondes. On dispose un collecteur (6) de métal liquide adapté à une sortie (20) de la colonne.
