Scrap Steel Refining: Separating Metals for New Steel

Message
[QUOTE="LAP3141, post: 6070360, member: 638707"] A lot of scrap steel is recycled to make new steel. But how is this scrap steel refined? Recycled scrap must be a mixture of various types of steel with each type containing different amounts of manganese, vanadium, chromium, etc. How are these other metals separated from the scrap melt so that new steels, such as 4140, which have a strict specification, be produced? The carbon additives can be oxidized out, but I'm not sure how the metallic additives can be separated. [/QUOTE]
