caustic soda leach of electric arc furnace dust

List of Abstracts

Significant secondary fume emissions are generated during tapping, slag raking, and casting processes at Eramet's C1F furnace in Marietta, Ohio, USA. The semi-open electric arc furnace can produce either SiMn, which is cast on sand, or high-carbon FeMn, from which slag is

Thermal plasma waste treatment IOPscience

Electric arc furnaces for melting of steel scrap produce a significant amount of dust, typically about 16 kg dust per tonne of steel, or up to 10 000 t/yr −1 for a typical mini-mill . With the increased production of steel in arc furnaces (approaching 40% of total steel production), the amount of dust has also increased, and the heavy metal

The spent liquor is processed through a recovery furnace where dissolved organics are burned to recover waste heat, sodium sulfide, and sodium carbonate. The recovered sodium sulfide and sodium carbonate are diluted with water and then treated with slaked lime to recausticize the sodium carbonate into sodium hydroxide (caustic soda) for reuse.
