    The research has also investigated the utilisation of iron ore mine tailings to replace conventional aggregates in concrete. 100% of both fine and coarse conventional aggregates were replaced with tailings in the mixed design. The concrete mix was casted into moulds and cured. It was found that the compressive strength of the concrete with

  • Ferrous Slag general information Euroslag

    Ferrous Slag general information. Iron and steelmaking slags (ferrous slags) are co-products of the iron and steel making industry. They are non-metallic rock-like materials which are produced together with the metallic products of these processes. Depending on the iron and steel production process different slag types can be manufactured.

Abstract: Iron ore cement is a product intended to be used in sea water work. This material is now manufactured in Europe under the name of Erz cement.

  • Utilization of Iron Ore Tailings as Raw Material for

    The cement industry has for some time been seeking alternative raw material for the Portland cement clinker production. The aim of this research was to investigate the possibility of utilizing iron ore tailings (IOT) to replace clay as alumina-silicate raw material for the production of Portland cement clinker. For this purpose, two kinds of clinkers were prepared: one was prepared by IOT; the

  • Iron ore Wikipedia

    Ideally iron ore contains only iron and oxygen. In reality this is rarely the case. Typically, iron ore contains a host of elements which are often unwanted in modern steel. Silicon. Silica (SiO 2) is almost always present in iron ore. Most of it is slagged off during the smelting process. At temperatures above 1,300 °C (2,370 °F) some will be reduced and form an alloy with the iron. The

    Utilisation of iron ore tailings in bricks as a replacement for sand will help in sustainable and greener development. The literature shows the potential use of iron ore tailings as a replacement

  • Iron Ore an overview ScienceDirect Topics

    R. Stace, in Iron Ore, 2015. Abstract. Iron ore reserves are normally found within a few meters from the ground surface, and most of the major mines of the world are operating an opencut system, which requires little sophistication, except in terms of the equipment used and the quantities needed to be mined for operations to be cost-effective. This chapter will look at case studies that define

  • Evaluation of iron ore tailings as replacement for fine

    Millions of tons of iron ore tailings (IOT); a by-product of iron ore processing, are disposed of every year in landfills, quarries, rivers, oceans among others thereby posing environmental problems. The major aim of this study is to evaluate IOT as replacement for river sand in concrete and compare with the result of conventional concrete. Concrete mixtures containing 25%, 50%, 75% and 100%

    Sustainable handling of iron ore tailings is of prime concern to all stakeholders who are into iron ore mining. This study seeks to add value to the tailings by utilising them as a replacement for

  • The Utilization of Slag in Civil Infrastructure Construction

    BF slag results from smelting iron ore, coke, and fluxes during the operations of extracting iron from the iron ore. Steel slag is formed during refining operations converting crude iron into steel by combining fluxes with the nonferrous oxides and other unwanted elements in the raw materials under molten state. Slag is a nonmetallic by-product containing dominantly CaO, SiO 2, MgO, and Al 2 O

The production amount of BF slag is approximately 300 kg per ton of pig iron, and that of steel-making slag is 100–150 kg per ton of molten steel

Figure 1: Main solid co-products by steelmaking routes2 An average value is shown for the EAF route (see Figure 1), as EAF plants often use a mix of DRI and recycled steel feeds. On average the production of one tonne of steel results in 200 kg (EAF) to 400 kg (BF/BOF) of co-products. These include slags, dusts, sludges and other materials. Ironmaking

  • Blast furnace slag Euroslag

    Blast furnace slag is formed during the production of hot metal by thermo-chemical reduction in a blast furnace. During this continuous process, iron ore or pellets as well as fluxes (lime[stone] and/or dolomite) are heated under reducing conditions in the presence of heated air. Coke and other reducing agents (e.g. injected coal) are combusted to produce []
