Iron pyrite, Fe 2 S, contains the iron, but it is difficult to isolate from the sulfur. This ore is used as a source for sulfur. This ore is used as a source for sulfur. A variation on pyrite is called pyrrhotite and the composition is written Fe 1x S. Iron also forms the sulfide marcasite, FeS 2 .
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 .
Usually where there is slag you'll find other pieces of slag. See if there are other similar pieces in the area, that can be a giveway. Ironnickel meteorites are usually strongly attracted to magnetic fields, and will also conduct electricity, so you can testing that as well.
Regrading slag to reduce slag/soil creep. Breaking up fused slag to increase root penetration (, "ripping" with a bulldozer). Mixing materials into the slag to improve water retention. Water retention amendment systems could be temporary, lasting long enough to establish plants with deep root systems, or permant, widening the range of species.
Steelmaking can also be classified depending on the starting material used. a) Primary steelmaking Furnace used for primary steelmaking. Limestone and dolomite are added as slag formers.
Blast Furnace Slag Material Description ORIGIN In the production of iron, iron ore, iron scrap, and fluxes (limestone and/or dolomite) are charged into a blast furnace along with coke for fuel. The coke is combusted to produce carbon monoxide, which reduces the iron ore to a molten iron product.
For typical iron ore grades (60% to 66% iron), a blast furnace will normally produce about to ton of slag per ton of crude iron. For ore grades lower than average, the slag output will be higher—sometimes as much as to t of slag per ton of crude iron.
In Kentucky, most of the brownred, ironlike specimens that are brought to the state's Universities for identification are manmade iron slag, rather than meteorites. Shiny, silvermetallic specimens brought in for verification as meteorites tend to be manmade metallic silica, which is a slag .
Pig iron is the metallic ore that contains 90% of iron. Pig iron is used for making steel and pure iron units. It has very high carbon content along with silica and another constituent of dross.
The waste slag can be used for road surfacing.
Iron ore is the key component in steel, the most widely used of all metals. In South Africa our iron ore operations are made up of a % shareholding in Kumba Iron Ore Limited (Kumba), a leading supplier of seaborne iron ore. Kumba is listed on the Johannesburg Stock Exchange and operates three mines.
Sep 16, 2008· the nost important use is to separate the silicon impurities as calcium silicate (slag) which floats on the molten iron and prevents reoxidation. It is periodically tapped off. When is forms solid it is broken up and can be used for road surfacing.

Mar 14, 2015· A bloomery is a type of furnace once widely used for smelting iron from its oxides. The bloomery was the earliest form of smelter capable of smelting iron. A bloomery's product is a porous mass of ...
The iron ore, pellets and sinter then become the liquid iron produced in the blast furnace with any of their remaining impurities going to the liquid slag. The coke is produced from a mixture of coals.
