Technological innovations in recycling of zinc concentrates

 

 

 

Key words: 

recycling, kiln process, zinc bearing waste.

Summary

The recycling processes become more popular while considering the implementation of sustainable development guidelines. The factors determining the development of recycling technologies include in first place an increase in environmental protection requirements, depletion of primary raw materials, increasing demand for secondary raw materials and related price level. Beside extractive industries the processing industry, especially the fuel and power generating and metallurgical industries play a predominant role in waste generation. Waste materials generated in the metallurgical industry differ in terms of chemical composition and in first place are reach in valuable elements and chemical substances that should be recovered to be reused for economic and ecological reasons.  Technological innovations in metallurgy and recycling of zinc concentrates have been characterized in this paper. Special attention has been paid to inspirational significance of the relevant BAT conclusions. The origin of zinc bearing waste generation and processing in Poland and the development of enrichment techniques based on domestic engineering solutions is described. Recycling of zinc concentrate from waste in the modified Waelz kiln process. The problems related to classification of  full-featured zinc concentrate obtained in this process are discussed in the light of the Act on waste, REACH regulation on registration, tariff and statistical nomenclature according to the Community Customs Tariff and Polish Product and Service Classification are discussed.
