   Sammanfattning : Pickling sludge generated in the stainless steel industries contains large amounts of calcium fluoride and water and relatively small amounts of metals. Therefore, such sludge is difficult to be directly recycled back to the EAF process and would be harmful to the environment if deposited as landfill for a long term. LÄS MER
