electrowinning gold oxygen aqua regia

REVIEWING THE OPERATION OF GOLD ELECTROWINNING

The main drawback of the treatment with aqua regia is the nitric oxide (NO) gas that evolves when the metal is digested. This noxious gas represents a major threat for the health and safety of the workplace. Apart from aqua regia, other corrosive reagents have been used or tested. For example,gold was dissolved into chlorine water (i.e., water

Aqua regia Wikipedia

Aqua regia (/ ˈ r eɪ ɡ i ə, ˈ r iː dʒ i ə /; from Latin, lit. "regal water" or "Royal water") is a mixture of nitric acid and hydrochloric acid, optimally in a molar ratio of 1:3. Aqua regia is a yellow-orange (sometimes red) fuming liquid, so named by alchemists because it can dissolve the noble metals gold and platinum, though not all metals.

The Chemistry of the Extraction of Gold SAIMM

For example, gold does not dissolve in either nitric acid (an oxidizing agent) or hydrochloric acid (a complexing ligand), but dissolves quite easily in a mixture of the two, aqua regia. Whether they are solid, in solution, or in the gaseous state, gold compounds are invariably bound covalently, and by far the majority are complexes. *
