Gold mining is very expensive industry and therefore opportunities
resulting in low cost gold production are needed, which is spurring the
utilization of secondary resources such as tailings and e-waste for gold
recovery. In this project, new electrochemical reactor designs for this
purpose are investigated. Additive manufacturing (AM, 3D-printing) will
be effectively utilized in the construction of the cell components
including especially electrodes. Electro-efficiency of the recovery
systems are maximized in order to increase the sustainability of the
novel processes. The expected main result is an environmentally friendly
closed-loop gold recovery system that provides a viable option for any
valuable/critical metal recycling from the secondary resources. Also,
important information will be achieved from the utilizing AM technology
in the production of complex geometries utilizing different starting
