The utilization of steel slag in cement includes mainly three modes [ 55 ]: matching the clinker of cement raw material, producing low-clinker steel slag cement, and being an active addition [ 55 ]. The process of making steel slag cement is a simple manufacturing technique with less investment and low cost.The viscosity measurement of FeO–SiO2–Al2O3–CaO–MgO synthesized slag via inner cylinder-rotation method revealed the effects of Al2O3, CaO, and MgO on the viscosity of FeOx–SiO2 (x = 1.0(PDF) Processing of Complex Materials in the Copper

Copper telluride slag from copper smelting process is an important source of tellurium (Te). In this work, an efficient and economical hydrometallurgical process for extracting Te from copper telluride slag was proposed. First, H2SO4 and NaClO3 were demonstrated to be effective for separating Te and Cu, and the leaching efficiency of Slag-matte systems are important in processing of complex Cu–Pb–Zn materials. Most of the previous studies have been focused on Cu and Cu–Ni slag-matte systems. Almost no data in laboratory-controlled conditions were found in the literature for the Pb–Cu–Zn slag-matte systems.Characterization of Phase Equilibria and Thermodynamics

The ratio, b, is so adjusted that it is less than, equal to, or greater than unity for acid, neutral, or basic slag, respectively. For a complex slag comprising CaO, MgO, SiO 2, and P 2 O 5, the basicity index may be further modified on the assumption that concentration of CaO and MgO are equivalent on molar basis. Converting this Moreover, other slag components also affect the dissolution process. For example, the structure of slag becomes more complex with an increase in the network formation (e.g., SiO 2) content in the slag. As a result, the viscosity and melting point of the slag increase, the fluidity worsens, and the oxide dissolution slows down.Characterization and mechanism of dissolution behavior of
