Abstract

In the recycling of steel, the galvanized and painted steel increases its proportion all the time and the zinc is collected mostly as dry or wet dust. When this dust is worked up, the halogens from the paint causes a problem. By evaporating zinc and halides and oxidizing the zinc and selectivey sulphatizing the halides, the halogens can be separated from the zinc oxide. Freedom of halogens increases considerably the value of the zinc oxide.
