What is Slag? (with pictures) - wisegeek.com

Mar 18, 2019· Non-ferrous smelting, used to refine copper, lead, and similar metals, produces highly ferrous slag, as iron is an undesired element. Ferrous smelting, such as that used to produce steel, creates non ferrous slag, as all the iron is used in the smelting process. After slag is allowed to age, it can be sold for use in other industrial processes.

Direct reduced iron: Direct-reduced iron (DRI), also called sponge iron, is produced from direct reduction of iron ore (in the form of lumps, pellets or fines) by a reducing gas produced from natural gas or coal. The reducing gas is a mixture, the majority of which is hydrogen (H2) and carbon monoxide (CO) which act as reducing agents.

­The more advanced way to smelt iron is in a blast furnace. A blast furnace is charged with iron ore, charcoal or coke (coke is charcoal made from coal) and limestone (CaCO 3 ­). Huge quantities of air blast in at the bottom of the furnace, and the calcium in the limestone combines with the silicates to form slag.

and smelting. For converting, the Pierce-Smith and Hoboken converters are the most common processes. The matte from the furnace is charged to con-verters, where the molten material is oxidized in the presence of air to remove the iron and sulfur impurities (as converter slag) and to form blister copper. Blister copper is further refined as ...

Slag - Wikipedia

In nature, iron, copper, lead, nickel and other metals are found in impure states called ores, often oxidized and mixed in with silicates of other metals. During smelting, when the ore is exposed to high temperatures, these impurities are separated from the molten metal and can be removed. Slag is the collection of compounds that are removed.

Blast Furnace Slag | National Slag Association

Blast Furnace Slag is formed when iron ore or iron pellets, coke and a flux (either limestone or dolomite) are melted together in a blast furnace.When the metallurgical smelting process is complete, the lime in the flux has been chemically combined with the aluminates and silicates of the ore and coke ash to form a non-metallic product called blast furnace slag.

History - Sloss Furnaces

GETTING STARTED In the years following the Civil War, railroad men, land developers and speculators moved into Jones Valley to take advantage of the area's rich mineral resources. All the ingredients needed to make iron lay within a thirty-mile radius. Seams of iron ore stretched for 25 miles through Red Mountain, the southeastern boundary of […]

USGS Minerals Information: Iron and Steel Slag

The iron ore is a mixture of iron oxides, silica, and alumina. From this and the added fluxing agents molten slag and iron are formed. The physical characteristics such as density, porosity, and particle size, are affected by the cooling rates and chemical composition.

By Rustu S. Kalyoncu - USGS Mineral Resources Program

Typically, for ore feed with 60% to 65% iron, blast furnace slag production ranges from about 220 to 370 kilograms per metric ton of pig iron produced. Lower grade ores yield much higher slag fractions, sometimes as high as 1 ton of slag per ton of pig iron. Steel slag outputs are approximately 20% by mass of the steel output.

Iron ore - Wikipedia

Iron ore is the raw material used to make pig iron, which is one of the main raw materials to make steel—98% of the mined iron ore is used to make steel. Indeed, it has been argued that iron ore is "more integral to the global economy than any other commodity, except perhaps oil".

Common Uses for Slag | National Slag Association

SLAG is a broad term covering all non metallic co products resulting from the separation of a metal from its ore, Its chemistry and morphology depends on the metal being produced and the solidification process used. Slags can be broadly categorized as ferrous (iron/steel) and non-ferrous (copper, lead/zinc) depending on the industry from which ...
