Utilization of biomass for blast furnace in Sweden

The Study of Ion Adsorption by Amorphous Blast Furnace Slag

In this study, the blast furnace slag was used as absorbing bed and then, its ionic adsorption was studied. For this reason, various experimental parameters such as pH, contact time and the primary ion concentration were investigated. The remaining concentrations of ions such as; Mn2+ and Fe2+ in water were measured by atomic adsorption spectroscopy. The chemical and p...

Ground Granulated Blast Furnace Slag

1. Ground Granulated Blast Furnace Slag Ground Granulated Blast Furnace Slag (GGBFS) is a by product of the steel industry. Blast furnace slag is defined as “the non-metallic product consisting essentially of calcium silicates and other bases that is developed in a molten condition simultaneously with iron in a blast furnace.” [1] In the production of iron, blast furnaces are loaded with iron o...

Effective Utilization of Blast Furnace Flue Dust of Integrated Steel Plants

Investigations were carried out on the effective utilization of blast furnace flue dust samples obtained from the two integrated steel plants at Rourkela and Jamshedpur. The samples essentially contained unburnt coke and iron rich grains as the value added products. Flotation technique was employed to recover the carbon values present in the sample. It was possible to obtain a product containin...

Rational Utilization of Fine Unclassified Tailings and Activated Blast Furnace Slag with High Calcium

The utilization of cemented tailings/paste backfill (CPB) by the mining industry is becoming increasingly important. However, it has been difficult to analyze the economic usage of CPB for fine unclassified tailings. Therefore, the physical and chemical properties of fine unclassified tailings, sampled from the Sijiaying Mine, were first analyzed in this study. After this, active excitation of ...
