Prospects for the Recovery of Finely Dispersed Gold …

The prospects for extracting finely dispersed gold and other useful components from the magnetic tailings of gold recovery plants and other sources are shown. This is achieved by using the process of leaching these particles and their extraction by sorption on metastable nanocrystalline water structures. A gold simulator, a colloid of molecular copper, is passed through the sorbent of a ...
