gold ore and citric acid releases

Chemicals LogiChem

Xanthates are used as flotation agents in mineral processing because they selectively link metal ore particles to air bubbles, this gives the precious metal, such as gold, buoyancy over the less valuable iron ore. The result allows the metal to be easily removed for further processing.

Aqua regia Wikipedia

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

Ammonia/nitric Acid Leaching of Copper Cobalt Oxidized

oxidised ore from Katanga has been investigated. Copper was leached in ammonia/nitric acid solution at room temperature. The effects of time, ammonia concentration, nitric acid/ ammonia ratio and pH, on the leaching kinetic of copper were investigated. Nitric acid was considered as alytic element to enhance copper leaching kinetic.

Aqua regia Wikipedia

The reaction with hydrochloric acid is an equilibrium reaction that favors formation of chloroaurate anions (AuCl 4 −). This results in a removal of gold ions from solution and allows further oxidation of gold to take place. The gold dissolves to become chloroauric acid. In addition, gold may be dissolved by the chlorine present in aqua regia.
