Gold processing - Mining and concentrating | Britannica

Gold processing - Gold processing - Mining and concentrating: The nature of the ore deposit determines the mining and mineral processing techniques applied. Oxide ore deposits are frequently of such low grade (e.g., 3 to 10 parts per million) that extensive mineral processing cannot economically be justified. In this case they are merely shattered by explosives and then piled into heaps for

Separation and Recovery of Gold(III), Palladium(II) and

Palladium(II), gold(III), and platinum(IV) can be successfully separated from the Pd-Au-Pt mixture in a 3-step stripping process. In the first stripping step, the aqueous phase should be treated with 5 M HNO 3 (Pt and 45% Pd separation), followed by the application of 0.5 M aqueous ammonia (Pd separation), and, finally, 0.1 M thiourea in HCl
