for separation of gold from scrap materials

diamond | GOLD

X-ray separation module for gold ore SM8-X is meant for separation of gold ore and for the separation of metal scrap and waste. Complexes: Modular separation complex MSC. The complex is designed for the separation of gold ores, base metals scrap and a metal waste of size 050 mm. Workshops: Preliminary dressing workshop.

Printed circuit boards from waste computers, televisions, and mobile phones were pyrolysed in a fixed bed reactor with the aim of separating and recovering the organic and metallic materials. A selection of printed circuit boards from each of the three waste classes was pyrolysed at 800°C and the pyrolysis products were analysed using GC-FID, GC-TCD, GC-MS, GC-ECD, ICP-MS, and SEM-EDX....

Electronic Scrap

Not all copper scrap contains gold, but it has been estimated by Boliden that about 4.4% of the total WEEE ends up as smelter-grade electronic scrap after sorting/separation, assaying 18.3% Cu, 670 g/t Ag, and 63 g/t Au. The treatment of this type of material has required the development of specialized equipment and technology at the smelter.
