what is a slag?

Answer 1

Slag is just a pile or rocks, or more importantly, excavated mine debris

Answer 2

There are two types of slags, metallurgical and natural slag. The first is a fused glassy material that is produced when a metal is separated from its ore during smelting. After smelting is an waste-recycling material, also called scoria. On the other hand, natural slag is a porous solidified lava that is ejected from a volcano

Answer 3

Slag is the waste product you get when you purify metal in a furnace, As the metal boils, impurities float to the top and you skim it off and throw it away on a heap hence slag heap.
chemical formula of slag is:
CaSiO3

also a slag is a derogatory term for a woman. sounds best when you say it in an east-london accent incidentally.

Answer 4

In Coal Mining, my grandfathers were both coal miners, slag was a pile that was built up from when the cars came out of the mine and were pulled out by two mini-horses and the pusher( that's what my dads dad did) every load of cars that came up would be pulled out by the horses and the pusher and taken by rail and dumped into a waiting train car. Small pieces of coal that fell off the cars on this journey were called "slag" after many years there would be a huge pile that would slope down from the entrance to the mine or "the hole" to the base of the mountain. It was mixed with the excavations into the mountain itself all the way to the coal vein mixed with the slag from the coal hoppers and this would be called the slag pile, typically seen in old western coal mines. So important were they that they wouldn't let them enlist in WWII

Answer 5

Where I'm from (Western Canada) a slag is another term for an insult. For example if you're slagging someone, it means insulting them.

Answer 6

1.Also called cinder. the more or less completely fused and vitrified matter separated during the reduction of a metal from its ore.
2.the scoria from a volcano.
3.waste left over after the re-sorting of coal.
–verb (used with object)
4.to convert into slag.
5.Metallurgy. to remove slag from (a steel bath).
–verb (used without object)
6.to form slag; become a slaglike mass.

Answer 7

Slags are the by-product of smelting ore to purify metals. They can be considered to be a mixture of metal oxides; however, they can contain metal sulphides and metal atoms in the elemental form. While slags are generally used as a waste removal mechanism in metal smelting, they can also serve other purposes, such as assisting in smelt temperature control and minimizing re-oxidation of the final bullion product before casting.

In nature, the ores of metals such as iron, copper, lead, aluminium, and other metals are found in impure states, 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. The collection of compounds that is removed is the slag.

Answer 8

From the way you are asking the question, I presume your reffering to a person being named a slag?

"Slag primarily used in the United Kingdom, to describe a woman (or recently a man) of loose morals who engages in casual sex and promiscuous behaviour, or a weak and pathetic male. Deriving from the term as used for the ugly piles (slag heaps) of impurities during the smelting of metals the term achieved a wider use with the comic strip The Fat Slags in Viz magazine. Nowadays, popular usage finds the word used in the context of referring to persons of any sex considered contemptible.

Slag is also a slang term meaning "insult" used in parts of Canada, the United Kingdom and Australia, and in Ireland, to slag someone off is to insult them.

In parts of Australia, the word slag is synonymous with "spit" as in saliva.

In the United Kingdom and New Zealand, to slag something or someone off is to disparage it or them in some way, constructively or not, usually to a 3rd party. For example: "This beer is crap", or "[Name of person] is a dweeb"

Also there is Slag as reffering to the waste created from the smelting of metals from their ore's.

Answer 9

Glassy material covering the weld during a Arc welding process which needs to be chipped off or cleaned.

Answer 10

Per Webster's New Explorer Large Print Dictionary: " Waste from melting of ores." (ie: coal, for example, is a type of ore).
