Talk:smelt

Request: definition of the meaning regarding the chemical process used to extract metals from metal ores. smelting --Connel MacKenzie 05:40, 2 Jan 2005 (UTC)

Not a noun
Surely under meaning three, fusing of metals, smelt is not a noun but a verb. If it is then, slag does not apply, slag is the waste material produced by the process of smelting. I'm not entirely sure about this so will wait a bit for any thoughts before removing the noun part altogether. --Kylemew 11:37, 25 July 2007 (UTC)


 * This was already in the entry when I came upon it - all I did was formatting. I've marked both the metalworking noun senses for verification. Thryduulf 20:01, 25 July 2007 (UTC)

Seeing the verifications (thanks Thryduulf), it is a noun and, digging a bit deeper, I found that it refers to the mixture (usually charcoal and ore) used for smelting. From here if anyone's interested. --Kylemew 16:13, 3 August 2007 (UTC)

 * I think it means the mixture used for smelting, usually ore and charcoal. Have I put this comment in the right place please? --Kylemew 15:48, 3 August 2007 (UTC)
 * Slag it seems is the waste product after smelting, so smelt is a noun but is not slag. I started from here. --Kylemew 16:21, 3 August 2007 (UTC)


 * The noun (1) sense is the output of the smelting process (sense 2). The smelt is the (semi-)liquid you get from heating up the ore, and the slag is the waste portion  of that output (often in the form of solid or semi-solid inclusions.)  You would take your smelt (sense 1) and then further refine or amend it into your desired alloy.  Hence, while the smelt may contain slag, it is not (just) slag.  Most of the quotes above that are metallurgical in context refer to the process.


 * I can't find a good illustrative quote in online sources at the moment, but here are some using the "result" rather than the "process" sense, for documentation purposes.


 * 1982, Raymond E. Kirk and Donald F. Othmer, Encyclopedia of Chemical Technology
 * The green liquor, ie, the solution obtained on dissolving the smelt, contains an insoluble residue called dregs...
 * 1997, Anthony Lawrence Kohan, Boiler Operator's Guide
 * ...[it] reacts with the smelt in the furnace...
 * 1998, Deanna J. Richards, Greg Pearson, National Academy of Engineering, The Ecology of Industry: Sectors and Linkages
 * Dissolving the smelt liberates some hydrogen sulfide and particular matter...


 * I haven't added these at the article, as the definition "slag" needs to be rewritten. --Jeffqyzt 16:11, 13 August 2007 (UTC)
 * Also, smelting is not solely confined to the production of iron; you can, for example, smelt lead ore to produce lead (don't breathe the vapors :-) --Jeffqyzt 16:16, 13 August 2007 (UTC)
