Copper Enrichment in Solid with Selective Reverse Leaching with Oxalic Acid
(Springer, 2020)
As the first part of a novel process proposed for copper extraction, selective dissolution of iron from chalcopyrite in oxalic acid solutions with hydrogen peroxide was studied. Despite the fact that both iron and copper ...
Pressure leaching of chalcopyrite with oxalic acid and hydrogen peroxide
(Elsevier, 2021)
This study investigated the dissolution behavior of metals from chalcopyrite concentrate in a pressure reactor system in the presence of hydrogen peroxide by oxalic acid leaching. The fact that the compounds formed by ...
Dissolution of Chalcopyrite in Presence of Chelating Agent and Hydrogen Peroxide
(Springer, 2021)
Chelating agents (e.g., EDTA, titriplex III, etc.) are very important salts as they can take a complex form with metal ions. This study investigated usage of titriplex III in presence of hydrogen peroxide for metal extraction ...
