Abstract:
We have developed an innovative technology for extraction of non-ferrous, rare and precious metals from complex, hard mineral, man-made and recycled materials. Technology is based on the combined use of electrochemical reactions in the amount for one reactor producing the leaching agent, and the reaction metal extraction into solution. The source of sulfur leaching agents in the alkaline solution used sulfur graphite composite electrode. Experimental data on the parameters of metal leaching, from complex raw materials, on the characteristics of solutions (pH, electrical conductivity) was obtained. As was evidenced how these parameters change using sulfur-graphite electrode as an anode and as a cathode. Leaching was performed at the different initial concentration of alkali in solution. The changes in the parameters (pH, conductivity of solutions, etc.) in the leaching of various materials, using sulfur-graphite electrode, was investigated. Application of sulfur-graphite electrode as a cathode and an anode led to the same results of sodium metal formation into solution, results that in this case may be increased by selective extraction of metals in solution.
