Due to a successful combination of technically economic and electrical characteristics, alkaline nickel-cadmium batteries are widely used in both industrial and domestic areas. The development of the technology for recycling and repossession of the exhausted small batteries and storage batteries is a vital problem worldwide, nevertheless, the process keeps going on and new methods of solving the problem appear. At present, there is no environmentally friendly and cost-effective technology which would allow the exhausted batteries to be recycled to manufacture products of proper quality. New method of production of cadmium from shredded cadmium-containing batteries with an electroslag remelting was proposed, investigated theoretically and experimentally. The method implies electroslag remelting of preliminary grinded and those that have undergone magnetic separation cadmium-containing accumulators, storage batteries and small batteries. The cadmium contained in the batteries is powder - like cadmium/cadmium oxide. The cadmium recycling method is based on the reaction between cadmium oxide and carbon.
