Abstract

The urgency of a question to which the given publication is devoted, is caused by necessity of increase of the efficiency of processing of the fulfilled alkaline Ni-MH batteries containing valuable, but toxic compounds of nickel, cadmium and copper. The basic direction of research had been chose hydrometallurgical processing of the oxygen-nickel electrodes’ active materials of the fulfilled alkaline batteries which advantage is the opportunity of technological process’ optimization by way of reception of a complex of nickel compounds and other compounds. The way of complex hydrometallurgical processing of the oxygen-nickel electrodes’ active materials, the representing closed cycle is described. The technological circuit of complex hydrometallurgical processing of the oxygen-nickel electrodes’ active materials of the fulfilled alkaline batteries, in particular nickel — iron accumulators is developed and patented. Realization of stages of the given technological circuit in laboratory conditions has allowed to receive X-ray pure end-products, such as monocrystal hexahydrate sulfate of nickel (retgersite), free from the organic impurity, meeting the requirements to materials of optical manufacture; hexahydrate sulfate of nickel — ammonium and nickel hydroxide (II). The highly dispersion graphite corresponding to requirements of GOST 10273–79 is received. The mass contents of graphite makes 99.9% that there corresponds to mark the GAK-1 — graphite for storage products of special purpose. The structural characteristic and an estimation of cleanliness of products was carried out with the help of methods of the radiographic and spectral analysis. Cleanliness of the received graphite and nickel hydroxide allow their reuse in manufacture of active materials of alkaline batteries.
