Автор Kozlov P. A., Zatonskiy A. V., Reshetnikov Yu. V., Girshengorn A. P., Ivakin D. A.

Research results and developments of technology of hydrometallurgical processing of baked waelz-fumes for the purpose of zinc and indium extraction and lead deducing in a lead concentrate are resulted. The technology is designed on processing of ~55–60 kilotonnes of oxide per year with use of existing equipment of hydrometallurgical shop of JSC “Chelyabinsk zinc plant”. Key parametres of technology and a choice of process flow diagram for leaching, influence of leaching parametres on extraction of indium is presented. Backing of waelz-oxide allows to reduce number and duration of leaching operation in comparison with not baked product after soda-water clearning. For baked oxide leaching is recommended to realize in two stages, thus received acid solution is suitable for extraction recovery of indium.
