    Waelz process is a method of zinc recovery from wastes containing this element. The main generated wastes in the Waelz proces are slags. The production of the „acidic” slag is caused because of silica sand used as a acidic flux. The sulfuric acid is formed during the oxidation of sulphides present in the slag. This acid may increase the heavy metals mobility in the environment. These wastes also contain neutralizing minerals protecting the acidification of environment. It was found that the „acidic” slags generated by „Bolesław Recycling” have buffering capacity, very important parameter in the case of their used as aggregate.
