Abstract:
In this research work, the technology of extracting copper powder from copper-containing solutions was studied. This paper provides information on the recovery of copper from sulfate solutions using iron scraps and the production of copper powder by electrolysis. The change in particle size when recovering copper powder with iron when the solution is heated from 30 ? to 90 ? was studied, and it was shown that an increase in temperature significantly affects the reduction of particle size. Studies were conducted on the change in current density when obtaining copper powder by electrolysis, and it was observed that when the current density is less than 5 A/m2, copper precipitates on the cathode without separating, and when the current density increases to 15-35 A/m2, copper is released as powder. In conclusion, both of the above methods are effective in obtaining copper powder from copper-containing technological solutions. Copper powder is more expensive than cathode copper, and its production is economically viable for metallurgical enterprises.
