Abstract (en)
[origin: WO0020121A1] The invention relates to a method for separating lead from coated glass, especially glass from discarded picture tubes or similar lead-containing glass-like material. To achieve an improved method that makes it possible to separate lead from coated glass with a very high level of purity and thus allow a complete recycling of said glass, it is suggested according to the invention that the discarded picture tubes are crushed and ground to achieve a finely grained powdered material, that the finely grained material formed is brought into contact with a solution of leaching medium whose task is to solubilise the lead component from the glass material, whereby the components thus separated are sorted from one another via processing by floatation.
