W artykule przedstawiono analizę składu ilościowego i jakościowego odpadów powstających przy produkcji wyrobów jubilerskich ze srebra. Zaprezentowano również wyniki badań wstępnych odzysku srebra z tego typu materiałów na drodze procesu flotacji. Badania prowadzono przy pomocy laboratoryjnego urządzenia flotacyjnego.

In the recent years we have observed a substantial development of technology used to recover noble metals from recyclable materials. For the denoted group of metals - because of a rarity of appearance of their raw materials, as well as energy consumption of ore meanings - recycling has become a necessity from a view point of ecology and economy. In numerous cases recycling allows to receive materials of high purity, which in turns enables a further use of it by low financial outlays. On account of the fact that there is a great variety of recyclable materials containing noble metable, both in terms of the content as well as their physical form (e.g. electronic elements, junctions, catalysts, abradants), it is necessary to work out methods of recovery proper for the denoted recyclable waste. The methods should guarantee a high level of recovering metals, as well as be environment friendly. For instance, the methods currently used to recover silver from the waste of electronic elements are hydrometallurgical ones. They consist in selective recovery of silver with the use of alkaline, cyanic or sulfate solutions. In all of the above methods there occur waste solutions of acids, bases and salts, the utilization of which is a serious problem in terms of currently obliging environment protection norms. In the article above the analysis of the quantity and quality composition of the waste coming into being as a result of the silver jewellery goods production has been presented. The results of the preliminary research of silver recycling from that type materials during the flotation process. The research have been by means of the laboratory flotation machine.
