Common Uses for Slag | National Slag Association
Slags aint Slags. 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,...
The Extraction of Iron - Chemistry LibreTexts
Extracting iron from iron ore using a Blast Furnace. The common ores of iron are both iron oxides, and these can be reduced to iron by heating them with carbon in the form of coke. Coke is produced by heating coal in the absence of air. Coke is cheap and provides both the reducing agent for the reaction and also the heat source.

IRON AND STEEL - chemguide
Slag is used in road making and as "slag cement" - a final ground slag which can be used in cement, often mixed with Portland cement. Cast iron. The molten iron from the bottom of the furnace can be used as cast iron. Cast iron is very runny when it is molten and doesnt shrink much when it solidifies.
EXTRACTION OF IRON IN A BLAST FURNACE reduction …
EXTRACTION OF IRON IN A BLAST FURNACE Iron is also below carbon in the reactivity series, so therefore carbon can be used to reduce it (note: reduction can also mean to remove the oxygen from a compound). This is done in a blast furnace. The most common ore of iron is called haematite (iron…

Special Wastes | Hazardous Waste | US EPA
Fossil fuel combustion (FFC) wastes are the wastes produced from the burning of fossil fuels (i.e., coal, oil, natural gas). These wastes can include fly ash, bottom ash, boiler slag and particulates removed from flue gas. During its assessment of the regulatory status of FFC wastes,...
What is a Copper Slag? (with pictures)
Oct 02, 2019 · Copper slag is a by-product created during the copper smelting and refining process. As refineries draw metal out of copper ore, they produce a large volume of non-metallic dust, soot, and rock. Collectively, these materials make up slag, which can be used for a surprising number of applications in the building and industrial fields.
Tailings - Wikipedia
The effluent from the tailings from the mining of sulfidic minerals has been described as "the largest environmental liability of the mining industry". These tailings contain large amounts of pyrite (FeS 2 ) and Iron(II) sulfide (FeS), which are rejected from the sought-after ores of copper and nickel, as well as coal.
