Abstract

Oppfinnelsen vedrører en fremgangsmåte for separering av bly fra belagt glass, spesielt glass fra kassene billedrør eller lignende glassinneholdende glasslignende materiale. For å oppnå en forbedret fremgangsmåte som gjør det mulig å adskille bly fra belagt glass med et høyt nivå av renhet og således tillate en fullstendig resirkulering av nevnte glass, foreslås det ifølge oppfinnelsen at de kassene billedrørene knuses og oppmales for å frembringe et finkornet pulvermateriale, at det fint oppmålte materialet som er dannes bringes i kontakt med en løsning av utvaskingsmedium hvis oppgave er å løse opp blykomponenten fra glassmaterialet, hvorved komponentene som således adskilles sorteres fra hverandre ved flotasjonsbehandling.The invention relates to a method for separating lead from coated glass, in particular glass from the picture tubes or similar glass-containing glass-like material. In order to achieve an improved process which allows separation of lead from coated glass with a high level of purity and thus permitting complete recycling of said glass, it is proposed according to the invention that the boxes of the picture tubes be crushed and ground to produce a fine-grained powder material. that the finely measured material formed is contacted with a solution of leaching medium whose task is to dissolve the lead component from the glass material, thereby separating the components thus separated by flotation treatment.
