How to Recover Minor Rare Metals from E-Scrapparts and Ta sinter with lead wire. This is very useful in terms of pretreatment for e-scrap recycling..Also in the case of metallurgical production, with its intrinsic potential of smelting, extraction, enrichment and separation methods, play an important role in the context of minor rare metals.

Gold Extraction from a High Carbon Low-Grade Refractory Gold Ore by Flotation-Roasting-Leaching Procing of flotation concentrate favorably made the removal rates of carbon and sulfur reach 99.81% and 98.79%, respectively. After roasting, the gold in the roasted product was further enriched to 29.70 g/t and the optimal gold cyanide leaching extraction reached 93.66%.

Gold Leaching from a Refractory Gold Concentrate by the Method of Liquid Chlorinationieved at 96.26% and 98% with most optimum conditions as follows: NaCl concentration 50g/L, NaClO concentration 200g/L, Liquid-solid ratio 10:1, the best reaction time was 150 mins. And these conditions should be guaranteed pH<8.0, ORP>900mV.

The Effects of Common Associated Sulfide Minerals on Thiosulfate Leaching of Gold (Carboxymethyl cellulose) could not only reduce thiosulfate consumption but also increase gold dissolution. The mechanism of this might be that CMC could restrict the decomposition of thiosulfate by cupric ions and the precipitates on gold surface.

Recovery of Platinum Group Metals Using Perovskite-Type Oxider rhodium at high temperature in air atmosphere. And the PGM contents in the oxide are determined by chemical analysis. Then a new recovery process of PGMs from wasted automobile catalyst, in which PGMs can be separate to each element, was designed.
