Metallurgical Slag an overview | ScienceDirect Topics

Metallurgical slags play an important role in the extraction and refining of metals. They are formed when a flux material, added to or included in the charge, reacts with unwanted minerals during extraction or smelting, or with the products of the oxidation of unwanted solute elements during refining.

Phase Composition and Formation Mechanism of Slag

In addition, the ternary phase diagram analysis of CaO–SiO2–Al2O3showed that the primary crystal phase of the slag is in the gehlenite region, and that the primary crystal region migrates to the calcium aluminate region with the increasing of Al2O3content, which are beneficial to the slag crust formation.

Multiple Slag Operation on Boron Removal from

The removal of boron from metallurgical-grade silicon by Na2O-SiO2 slag refining was investigated. The final content of boron in refined silicon was examined under different conditions of temperature, slag composition, holding time, mass ratio of slag to silicon, and slag refining times. The content of boron in silicon decreased from 10.6 to 0.65 ppmw by slag treatment in one time, and

Leaching kinetics and mechanism of slag produced from

01.08.2020· In the present study, we investigate the kinetics and mechanism of the leaching of calcium aluminate slag in Na 2 CO 3 solution for alumina recovery. The slag consists of leachable phases, e.g., 12CaO·7Al 2 O 3, CaO·Al 2 O 3, 5CaO·3Al 2 O 3, and a non-leachable phase that contains Ca-Al-Si-Ti oxides.A series of leaching treatment is done at different temperatures, leaching times, stirring

12.07.2004· The reaction mechanism can be presented by the following reactions: 1. ozone decomposition (1) O 3 + M 2+ SL → O − M 2+ SL + O 2 (2) O 3 + O − M 2+ SL → M 2+ SL +2 O 2 where M 2+ SL is the catalyst, i.e. metallurgical slag modified by a metal ion. 2. catalytic reaction (3) O − MSL + R → MSL + RO where R represents C 6 H 6 or CO. Since the oxidation is based on ozone

Green Transforming Metallurgical Residue into Alkali

Silicomanganese slag is a solid waste in metallurgical industry and can be transformed into an alkali-activated silicomanganese slag-based cementitious-material (ASSC) for the first time. The ASSC shows quite low electro-conductivity and can be raised dramatically by incorporated carbon black (CB) in the matrix of ASSC to create an electro-conductive alkali-activated silicomanganese slag-based
