Outokumpu Technology and Erdenet Mining Corporation have signed a Memorandum of Understanding for building an industrial scale HydroCopper plant in Erdenet, Mongolia.
The new plant will be designed to produce 35,000 tons copper annually.
The HydroCopper process is Outokumpu's new, advanced technology to produce copper directly from copper concentrate at the mine site.
Outokumpu has studied hydrometallurgical process routes for copper recovery from sulphide concentrates, both in sulphate and chloride environments, for many years.
The innovative development has given rise to an unconventional and beneficial process concept, the Outokumpu HydroCopper process.
In the new concept copper is produced with the help of a standard chlor-alkali plant.
The process consists of three main areas: leaching of concentrates, making of copper products and regeneration of chemicals.
To verify the technology Outokumpu has designed and constructed a demonstration plant in Pori, Finland.
The benefits of chloride leaching processes are astonishing.
Modern chlor-alkali cell with a high intensity makes the process closed and compact.
The process directly produces a commercial high quality final product suitable for demanding purposes.
The process has been designed to meet the highest demands both in safety and environmental aspects.
