Dec 07, 2013· 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. Iron-nickel meteorites are usually strongly attracted to magnetic fields, and will also conduct electricity, so you can testing that as well.

After removing the slag, the molten pig iron is blown with oxygen to form a new slag containing 12–24 percent vanadium pentoxide (V 2 O 5), which is used in the further processing of the metal. Vanadium is extracted from carnotite as a coproduct with uranium by leaching the ore concentrate for 24 hours with hot sulfuric acid and an oxidant ...

Iron processing, use of a smelting process to turn the ore into a form from which products can be fashioned.Included in this article also is a discussion of the mining of iron and of its preparation for smelting.

George C. Wang, in The Utilization of Slag in Civil Infrastructure Construction, 2016. Abstract. Molten blast furnace (BF) slag and steel slag are produced simultaneously with iron and steel manufacturing. BF slag results from smelting iron ore, coke, and fluxes during the operations of extracting iron from the iron ore.

The first pressed glass pieces that collectors refer to as "slag glass" were made in the 1890s, using the glass-like by-product of iron ore known as—you guessed it—slag. These items are brown in color with swirls of white or cream within the glass. Other types of metal ores produce different colors of slag .
