Alumina-rich iron ore is a widely existed polymetallic deposit in the nature, and it has a high comprehensive utilization value. Because the alumina and iron contents of alumina-rich iron ore vary from each other, there are many different measures and processes to recover iron and alumina from the various kinds of alumina-rich iron ore. In the blast furnace (BF) ironmaking process, the alumina ...

The present study deals with the utilization of fines generated from comminution process (crushing, grinding and screening) of the Run of Mines into value added products i.e. fluxed iron ore pellets. The study comprises to understand the physical and mechanical behavior of five distinguished chemical compositions of green and dried iron ore pellets with respect to a typical Mini Blast furnace (...

The purpose of this study was to assess the physical and mechanical properties pavement concrete for rural roads South Korea made with air-cooled slag aggregate, which is an industrial byproduct. This assessed chemical according following performance requirements based on design criteria Ministry Agriculture’s Agricultural Production Infrastructure Maintenance Business Plan Expressway Corporati...

In order to investigate the influence of SiC on composition and structure mixed slag (blast-furnace slag: steel = 1:9), chemical composition, equilibrium-phase microscopic morphological characteristics elemental distribution in region SiC-reagent-tempered samples were analyzed by X-ray diffractometer (XRD), FactSage7.1 thermodynamic analysis software, scanning electron microscope, energy spectr...

Heat treatments are applied to orthodontic wires in order to relieve the stresses arising during orthodontic work. Four types of wires were heated in air, argon or vacuum environments, and cooled in the furnace or in a water bath. The susceptibility to corrosion and mechanical properties of the heat-treated wires were investigated. Heat treatment marginally increased the yield strength and elas...

Alkali Activated Slag Concrete (AASC) mixes are manufactured by activating ground granulated blast furnace slag (GGBFS) using sodium hydroxide and sodium silicate solutions. The aim of the present experimental research was to investigate the effect of increasing the dosages of sodium oxide (Na2O, in the range of 4 to 8%) and the activator modulus (Ms) (i.e. the SiO2/Na2O ratio, in the range of ...

Different ways of combining argon oxygen decarburisation slag (AOD) or electric arc furnace slag (EAF) with blast furnace slag (BFS) for achieving better phosphorus (P) removal performance in small-scale wastewater systems (SSWSs) were examined. The three types of slag were combined in varying mass ratios and with different dosing procedures in batch experiments using synthetic solution and rea...
