    Enabling the recycling of E,  · Elementary retraction avoids these issues and aims to recover these materials by heating them to fairly high temperatures in a reactor, exceeding their melting points, up to 1450 C. This causes plastics to be incinerated and the metals to melt or vaporize (e.g. zinc and cadmium, both commonly found in batteries, have boiling points of 907 °C and 767 °C respectively).Lead smelting,  · The crude bullion and lead slag layers flow out of the 'furnace front' and into the 'forehearth', where the two streams are separated. The lead slag stream, containing most of the 'fluxing' elements added to the sintering machine (predominantly silica, limestone, iron and zinc) can either be discarded or further processed to recover the contained zinc.
