Currently, the general processes of recycling cutting tools involve acid dissolution and separation processes that adopt the principle by utilizing the insoluble characteristics of diamond and tungsten carbide, while dissolving metals. After the filtration of valuable particles, the solution that carries dissolved metal ions are discarded [5,6]. This study offers not only recovering diamond and other valuable particles, but also recycling of metals by co-deposition of metal powders. The waste cutting tools used as anode dissolves in relatively weaker acidic electrolytes and metalic parts are collected as powders at the cathode while hard particles sink to the bottom of electrolyte when power is applied. Temperature, current density, acid concentration and CuSO4concentration of electrolyte are the process parameters to optimize microstructure, density and surface area of metallic powders. It was found that decreasing current density resulted in a more compact and dense powders as it can be seen in Figure below.
