  Processing and Reusing Technologies for Steelmaking Slag

  201394 · The iron/steel slag processing flow is schematically shown in Fig. 2. Steelmaking slag is subjected to the following four process-es: ① solidify and cooling of the hot molten slag, ② crushing and magnetic separation treatment of the slag to recover the metal iron, ③ crushing and classification of the slag for grain size adjustment

  Technological scheme for copper slag processing

  2017110 · A technological scheme for copper slag processing is proposed. It comprises 5 stages, namely: (i) air oxidation of the copper slag at a temperature above 800 °C for 2 h; (ii) hydrothermal treatment of the oxidized slag with sodium hydroxide solution (140 g/l) at 190 °C for 3 h; (iii) separation of the solid from the liquid phase by hot filtration; …

  Efficient separation of iron elements from steel slag based …

  202331 · 1. Introduction. Steel slag is a by-product of the steelmaking process. In fact, each ton of steel produces 110–150 kg of steel slag. China's steel slag reserves are more than 300 million tons, and the annual hoard continues to increase [1].Due to the different steel composition, scattered varieties of converter slag and complex composition exist, …

  Separation of vanadium and chromium from vanadium-chromium slag …

  2024525 · Most V-Cr slag comes from converter slag with the temperature of 1500 °C. Na 2 CO 3 is added into converter slag at a high temperature of about 1000 °C and mixes them well. Then they are heated up to 1400 °C and held for 2 h. Thus, it can further save electricity or gas costs. Favorable vanadium-chromium separation is a low-carbon …
