Sources of creation and processing of zinc secondary raw materials
Abstract
Zinc is a widely applicable metal and therefore the different composition and form of zinc waste is generated. The most important waste material generated in production and processing of zinc is scrap metal of zinc and its alloys, as well as slag, dust and sludge from the production and processing of cathode zinc and zinc alloys. In terms of processing technology, there are different applied procedures depending on the type of raw material. The processing of waste zinc and its alloys is pyrometallurgical and it is based on remelting of dry and degreased raw materials, with alloying during melting to correct the composition. Zinc dust and sludge are processed by Waelz procedure, where the zinc-oxide is obtained and further being processed usually by hydrometallurgical procedure. The zinc and brass slag are grinded, followed by separation metal and oxide components. Large, predominantly metal fraction is being directly melted to obtain zinc or brass. Small, predominantly oxide phase is s...ubjected to hydrometallurgical treatment for zinc valorization.
