Recovery of heavy metals from electroplating wastewater
Thread Content
The precious metals present in the waste liquids generated during the electroplating of gold, silver, nickel, chromium, and copper have great value for recovery. What is the most effective recovery method available to date?
The chemical-metallurgical technology for the comprehensive recovery of heavy metals from multi-component electroplating sludge containing Cu-Ni-Zn-Cr-Fe and other elements (as well as heavy-metal sludge from other industries) and from acid pickling waste streams, while simultaneously eliminating environmental pollution, involves the processes of acid decomposition, ammonia complexation in ammonium sulfate medium, and ferrite formation.
