The resource utilization and stabilization disposal of stainless steel pickling sludge has received more and more attention from domestic and foreign scholars. Here, a sustainable treatment process of low-silica reduction smelting for stainless steel pickling sludge, followed by low-temperature vitrification for the reduced slag, has been proposed. The metal yield can …

Followed the stainless steel meshes were dip-coated by the mixture for several minutes, and then dried at 75 °C for about 2 h. Finally, the highly hydrophobic stainless steel meshes were obtained by this one-step dip-coating procedure. 2.4. Oil–water separation experiment. The prepared stainless steel meshes were fixed between two glass tubes.
