| Abstract: | Reclaiming cadmium from sediment of smelting zinc industry is in favor of increasing economic benefit and improving entironment. In this paper, the experiment on displacement of cadmium by zinc's powder, zinc's piece and zinc's granule was performed. A new technique of displacement of cadmium by zinc's piece was invented, and the technics and conditions of extraction was researched. The sponge cadmium whose purity was over 90% was retrieved. |
