Abstract

Recikliranje metala i njihova industrijska upotreba postupno zauzimaju vaņno mjesto u svijetu kako zbog očuvanja prirodnih resursa i sve potrebnije zańtite okolińa, tako i zbog smanjenja trońkova proizvodnje metala. Materijali na bazi titana imaju odreĎene karakteristike koje ih čine promjenjivim u različitim granama industrije, a zbog neograničenog vijeka trajanja postaju izvrstan resurs za recikliranje. Krollovim procesom, glavnim postupkom dobivanja titana, stvara se kloridni otpad (MgCl2) koji se po nastanku uklanja recikliranjem, pri čemu se dobiveni metalni magnezij i plinoviti klor primjenjuju u daljnjoj industrijskoj proizvodnji titana. Recikliranje titana i njegovih legura ima pozitivan učinak na okoliń, a za njegovo recikliranje je potrebno i manje energije. Karakteristični reciklaņni procesi za proizvodnju titana i njegovih legura su ekstrakcija te recikliranje u plazma pećima.

Abstract (english)

Recycling of metals and their industrial use gradually occupy the important place in the world due to preservation of natural resources and necessary environmental protection ensurance, as well as due to reduction metal production expenses. Titanium-based materials have certain characteristics which enable theirs application in different branches of industry. Due to their unlimited lifetime (end of life - EoL) titanium materials became an excellent resource for recycling. By Kroll's process, as the main method for the titanium production, chloride waste (MgCl2) is produced. During recycling process, extraction of metallic magnesium and gaseous chlorine occurred and used in further industrial production of titanium. The recycling of titanium- based materials has a positive effect on the environment, and its recycling used less energy. Characteristic recycling processes for the production of titanium and its alloys are extraction and recycling in plasma furnaces.
