| Abstract: | Plasma melting technology in the industrial application field of precious metals recycling from secondary resource are summarized, the process flow of plasma melting and the process of plasma melting tail gas treatment are introduced, and the principle of iron capture platinum group metals are preliminary analyzed. Through industrial test of a certain scale has got the preliminary process conditions for plasma melting iron capture technology from secondary resources material enriching of platinum group metals, the recovery rate of platinum, palladium reached 98%, rhodium over 97%. It has proved that the plasma melting iron enrichment platinum group metal capture technology has advantages with environmentally friendly, higher platinum group metals recovery rate, and wide adaptability, etc. |
