Using a commercially available solvent impregnated resin, Lewatit TP272, in an ion exchange process, it was possible to extract up to 90 % indium from a feed containing as little as 1 mg/L indium in the presence of high amounts of impurities, i.e. 10

Automobile exhaust catalysts and electronic equipment, for instance, are rich in platinum group metals (PGMs). At the end of their lifecycles catalytic converters are smelted in electric arc furnaces (EAF) for PGM recovery. With approx. 40 ppm, PGM d

Multicomponent nanopowders can be produced using vapor phase ammonolysis of SiCl 4 /TiCl 4 mixtures at 800°C and 1000 °C. Uniform particles with spherical morphology and diameters between 150 nm and 350 nm are obtained. At 800 °C, crystalline TiN
