Hydrogen Peroxide Market for Gold Extraction Global
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. By using hydrogen peroxide, the extraction of gold is reasonably economical and eco-friendly compared to other extraction methods. The hydrogen peroxide market for gold extraction is driven by the
Improvements in gold ore cyanidation by pre-oxidation
01/07/2017· Previous experience in other gold extraction plants indicated the possibility of the use of hydrogen peroxide (H 2 O 2) for the purpose of pre-oxidation. AngloGold Ashanti's Siguiri plant in Guinea introduced oxygen supplementation via H 2 O 2 injection in the cyanidation circuit, and that resulted in an improvement in overall plant gold recovery from ∼90% to ∼94% ( Verster, 2016 ).
