99% of all meteorites are attracted to a strong magnet. (As are metal artifacts, slag and iron ore) Or if the object is small, hang it or the magnet from a string. This is used as a preliminary test and is recommended to new collectors. If your specimen does not pass this test it is probably NOT a meteorite!
Blast furnace slag is recovered by melting separation from blast furnaces that produce molten pig iron. It consists of non-ferrous components contained in the iron ore together with limestone as an auxiliary materials and ash from coke. Approximately 290 kg of slag is generated for each ton of pig iron.
Generic Mineral Wool . Product Selection and Description . Blown mineral wool insulation is made by spinning fibers from natural rock (rock wool) or iron ore blast furnace slag (slag wool). Rock wool and slag wool are manufactured by melting the constituent raw materials in a cupola.

Nov 09, 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.

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.
then reacts with the iron ore to form carbon dioxide and pure iron. Separating the iron from the slag 2 The melted iron sinks to the bottom of the furnace. The limestone combines with the rock and other impurities in the ore to form a slag which is lighter than the iron and floats on top.
which produce the types of iron slag most likely to be found on archaeological sites in both rural and urban areas. Smelting is the production of iron from ore and fuel in a smelting furnace. The products are spongy mass called an unconsolidated bloom ‐ raw iron with
Jun 27, 2014· Some slag is formed (glasslike) in the processing of iron ore into iron or steel, this appears to be a piece of that material. It's fused limestone and other stuff. Not really glass at all. It does have conchoidal fracture, as this exhibits.
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.
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.
