Gold cyanidation using hydrogen peroxide ScienceDirect

in which hydrogen peroxide, formed as an intermediate product in the first step, becomes the oxidising agent in the second .. Generally, in mining, atmospheric oxygen acts as the oxidant agent in gold cyanidation, but its solubility in the leaching solution is so limited that it makes the processes slow and the cyanidation rate is then determined by the oxygen concentration in the leaching

gold leaching. The effects of free and complexed iron and copper catalysts on the oxidation and consumption of hydrogen peroxide and cyanide were also investigated. It was shown that the cyano complexes of Fe(II) and Cu(I) are also effective as decomposition catalysts. Hydrogen peroxide concentrations above 0.01 M decreased the free cyanide

Using Hydrogen peroxide in ore Gold Refining Forum

Some miners here in our place are using Hydrogen peroxide on ground ore for the purpose of leaching any copper on the ore. After this they put Sodium cyanide to leach silver and gold. They basically mix ground ore with lime in the vat leach. Then they put hydrogen peroxide with water and after some time, they let go of the solution as waste.

Hydrogen Peroxide Market for Gold Extraction Global

Hydrogen peroxide is used in the mining industry for the extraction of precious metals such as gold, platinum, and palladium. Gold extraction from natural sources, including gold rocks and gold ores, can be done by leaching the gold concentrate or crushed gold rocks, in a solution of hydrogen peroxide and hydrochloric acid.

Gold cyanidation using hydrogen peroxide, Hydrometallurgy

Gold cyanidation, using hydrogen peroxide as an oxidising agent, has been studied by performing kinetic experiments, open circuit potential measurements and voltammetry. Small amounts of hydrogen peroxide make the cyanidation rate lower than that in conventional cyanidation, but higher amounts can make the cyanidation rate double.

Hydrogen Peroxide in CIL Gold Leaching Circuit

The effect of hydrogen peroxide on gold leaching rates in alkaline cyanide solution is a matter of controversy and debate. Early studies indicated that the reduction of hydrogen peroxide on gold surfaces is kinetically hindered, and the dissolution rate of gold in oxygenfree solutions containing hydrogen peroxide is very slow.

Technical Note Development in gold leaching using hydrogen

shown that hydrogen peroxide can be used as a source of oxygen in the leaching of gold ores. To avoid side reactions, the following conditions must be applied: Hydrogen peroxide must be diluted before it is added to the pulp. The dosage of HZO, must be properly regulated based on the oxygen level of the pulp.
