Electrochemical Extraction Of Gold From Wastes As

A simple one-step method for the extraction of gold from wastes as nanoparticles stabilized by phospholipids is demonstrated. This is achieved by applying an AC voltage for 5 s to the gold-containing wastes, which act as the electrodes in a buffer solution containing a dispersed phospholipid 1,2-dioleoyl-sn-glycero-3-phosphocholine, DOPC.This is an environmentally friendly and rapid method .

Us9051626b2 Method And A System For Gold

The invention relates to a method for the extraction of precious metals, using halogens. It has been found that introducing halogens in the reactor in the form of hypohalites rather than free halogens simplified greatly the recycling of halogens by electrolysis. It increases the rate of addition of the halogens and significantly reduces secondary reactions with base metals such as iron.
