STUDY OF ZINC AND LEAD THERMAL REDUCTION FROM A STEELMAKING SLUDGE

Popis výsledku v původním jazyce

The influence of varying thermal treatment conditions on reducing zinc and lead content from a steelmaking sludge was studied. The Waelz process in a laboratory rotary kiln was used for the experiments. It was found that the level of zinc and lead reduction strongly depends on used atmosphere and the reducing element used. A significant reduction of the zinc and lead content (well below 1 wt. %) was achieved at temperatures of 1,000 °C, respectively. A neutral atmosphere and high graphite content reduced the zinc and lead very efficiently. A nitrogen atmosphere caused the reduction of zinc and lead even without the use of an additional reducing agent; the carbon contained in the sludge was used for the reduction.
