The dominating copper phases in the slag are Cu, Cu2O and CuFeO2 (XRD and SEM-EDS). Leaching copper from these phases using sulfuric acid has a fast dissolution kinetics. Smaller par-ticle size, higher temperature (up to 40 C) and increasing mixing power (up to 0.26 kW/m3) enhance the leaching kinetics.

Steel slag has been proven to be an effective environment remediation media for acid neutralization, and a potential aid to mitigate acid mine drainage (AMD). Yet its acid neutralization capacity (ANC) is …

In this study, sulfuric acid modified steel slag (SS-HS) was prepared using a one-step hydrothermal synthesis method, utilizing converter steel slag as the raw material, to remove heavy metal Pb 2+ from water. Single-factor experiments were conducted to determine the influence of different factors on the adsorption capacity. The obtained …

In this study, geopolymer is prepared from 'ground granulated blast furnace slag' (GGBS)–a powder from grinding the by-product of slag waste from blast furnace of steel plants. For comparison, conventional cement, Portland pozzolana cement (PPC) containing fly ash was considered. To achieve simultaneous acidic and sulphate attack, …

Abstract. The extraction of vanadium from mechanically activated converter slag was studied in dilute sulfuric acid solution. The effects of roasting and leaching parameters were investigated. The results show that Ca/V mole ratio, roasting temperature, leaching temperature, S/L ratio and leaching time significantly affected the dissolution of ...
