Early comments

• just a short comment. Slag is not only produced by metallurgy industry, but is also coming from coal fired power plants. In some countries that is the mayor part of industrial waste. 11:34, 19 October 2005 User:217.40.27.9

This should be referred to as fuel ash. Peterkingiron (talk) 16:15, 12 December 2011 (UTC)

• Slag is a metal oxide. Some times, it has other impurities like S, P, Si etc but the major component of a slag is that its composition is mainly oxidized metal or oxidized metals. 21:26, 1 June 2006 User:149.135.12.112

No necessarily metal oxides, Commonly SiO2 is a major constituent. Peterkingiron (talk) 16:15, 12 December 2011 (UTC)

• Why is there a link on the bottom of this page to Great Yarmouth? 20:40, 5 December 2006 User:66.61.61.224

No clue - removed the link, if someone had a reason then put it back (and explain relevance here please). Vsmith 00:31, 6 December 2006 (UTC)

In steelmaking areas, basic slag is an important type of fertilizer for farmers and gardeners because of its phosphate content. It is distinct from other types of slag such as blast furnace slag. Anthony Appleyard (talk) 14:47, 22 March 2008 (UTC)

According to the basic slag article it comes from the Bessemer process and this article talks about slag in general so I don't see how this isn't inclusive. --Wizard191 (talk) 14:12, 23 March 2008 (UTC)

Question

If you are using 18,000 lbs lime a heat and reduce it to 14,000 a heat and the lime in the slag goes up. Why does this happen? —Preceding unsigned comment added by Slag101 (talk • contribs) 02:20, 11 July 2008 (UTC)

Error?

"basic slag must contain at least 12% total phosphoric acid (P₂O₅)" – the chemical formula if fishy. Phosphorus pentoxide reacts with water violently, so this is probably an error. Vadim Makarov (talk) 08:32, 30 November 2008 (UTC)

The reported temperature of 2600 degrees under "Modern slag uses" is clearly a conversion error and should be Fahrenheit and not Celsius: BF slag is tapped around 1500 degree C and cools in the runner to something like 2600 degree F at granulation [H. Saxen]

Done. Wizard191 (talk) 14:54, 25 November 2010 (UTC)

Other uses

One use of slag I didn't see mentioned is road treatment. Where I live they used to spread it on roads in advance of winter weather to improve traction. I don't know if it's still used for that purpose anywhere, but as school kids we loved to hear "the slag trucks are out" on the news because it meant no school tomorrow. —Preceding unsigned comment added by SquareWave (talk • contribs) 16:02, 19 January 2009 (UTC)

Volcanic slag

The volcano article on Tuff mentioned that small-scale tephra (volcanic ash) is "slaggy" and linked to Slag. Can any more to be said about that here, such as what in particular makes them "slaggy"? —Preceding unsigned comment added by 78.151.125.209 (talk) 06:56, 27 January 2009 (UTC)

Assessment

There are a number of types of slag, derived from different metallurgical processes. Some are glassy; others are not. I do not feel this article yet provides an adequate coverage. Peterkingiron (talk) 16:12, 12 December 2011 (UTC)

Illegal use of slag !

Occasionally one reads stories of pieces of slag sold at exorbitant prices as pieces of meteorite. Old_Wombat (talk) 09:52, 16 January 2012 (UTC)

Uses

Steel slag + Carbon Dioxide = Precipitated Calcium Carbonate. [1] 78.149.18.53 (talk) 22:59, 21 September 2014 (UTC)

WikiProject

Hello everyone. My name is Kiera Tran. I will be editing this Slag Wikipedia as my WikiProject in this semester. Please talk to me if there is something that we are disagree about during my editing period. Thank you! Ntran75 (talk) 18:01, 30 September 2021 (UTC)

Slang usage

The article completely fails to mention that slag is a common British pejorative slang term for a promiscuous and sexually unselective woman, broadly equivalent to slut in American English usage (slut mostly retains its original meaning of a lazy or slatternly woman in BE). See The Fat Slags. --Ef80 (talk) 16:42, 30 November 2021 (UTC)

Totally irrelevant to the subject. If there was an article about the slang usage ... then maybe a disambig link would be justified ... but there is none. Vsmith (talk) 03:11, 4 December 2021 (UTC)

@Vsmith Then, why not create one that redirects to slut ? 85.193.252.19 (talk) 00:26, 5 December 2021 (UTC)

Of course it's not 'totally irrelevant'. We should at least have a one line link at the start of the article, perhaps directing readers to slut, though the meaning of that is somewhat different in British English. As things stand, non BE readers are going to find 'slag' in British material and are going to come here to find out what it means. There is nothing to enlighten them at present. --Ef80 (talk) 11:26, 4 December 2021 (UTC)

@Ef80 Though English is not my first language, it became my hobby. But, when possible, I use American English. I knew the word "slut" very well, but had no idea about the slang usage of "slag" in British English. I discovered your deleted post by accident, and thought immediately: Why is there no disambiguating link in the article? But, the more important question was: Why has your post been deleted? The User:Wtshymanski's revert summary was: "articles are about their subjects; talk page is for discussion of this subject. Not Wiktionary." But this is only partially true, because the biggest problem is with the very name of the subject. A reader has every right to be informed about other meanings of an article title, especially when one of those meanings is unexpected. After all, what are disambiguating links for? 85.193.252.19 (talk) 21:47, 4 December 2021 (UTC)

I have added a disambig hatnote linking to slut. --Ef80 (talk) 16:26, 15 December 2021 (UTC)

Silently reverted by our friend User:Wtshymanski, who appears to have WP:OWN issues with this article. I don't need grief like this over such a trivial matter, so am walking away. --Ef80 (talk) 11:29, 18 December 2021 (UTC)

Ï've put this back. Nothing "unlikely" about the term if it's in widespread use elsewhere online - possibly more so than the original meaning. 66.102.87.40 (talk) 13:20, 8 January 2022 (UTC)

Dustfreeworld and reverts

@Dustfreeworld Let's talk about how your video is relevant to this topic. While yes, slag may be used in some roads and construction, we do not know if that road was made in this way. Further, your source mentions roads in the USA but the video is sourced from Hong Kong. This seems too tenuous a connection. You need to show that the image content itself is directly relevant to Slag.

I would like a more experienced wikipedian to weigh in on this. Also, I want to bring WP:NOBLECAUSE to your attention, because of your username and multiple reverts on this same subject. 129.224.209.91 (talk) 18:18, 19 December 2023 (UTC)

P.S. Please be aware of WP:3RR if anyone else decides to remove this file link, as you have already reverted this before. 129.224.209.91 (talk) 05:38, 21 December 2023 (UTC)

I don’t understand what you mean, I’m not the one removing file link, I’m the one who restoring file link.

Disregard this, I was mistaken about the Three Revert Rule. It is about reverts taking place within 24 hours, not necessarily regarding the same edit. 129.224.209.91 (talk) 05:38, 21 December 2023 (UTC)

Hi IP. First, please note that the title of the article is not “Slag in the United State”.

Second, please note the text in the article that goes with the video: “Fine slags and slag dusts generated from milling slags to be recycled into the smelting process or upcycled in a different industry (e.g. construction) can be carried by the wind, affecting a larger ecosystem. It can be ingested and inhaled, posing a direct health risk to the communities near the plants, mines, disposal sites, etc.”

Third, do you mean in an article like “chlorophyll”, if someone wants to add an image of a leave, with caption saying something like “leave is where photosynthesis occurs”, they first need to submit a report supporting that the leave contains chlorophyll and the leave is located in the U.S.?

Further, while you edit as an IP with NO user name, how can we know if you have any COI / “noble cause” or “not-that-noble-cause”? I’ve seen people from the construction industry and power tool Industry editing tendentiously here. I hope you aren’t one of them.

As for your asking for more experienced editors to weigh in, I suppose right or wrong isn’t determined by experience, if it is, I think I’m a much more *experienced user* than an IP. BTW, please sign you post.

Thanks and regards, --Dustfreeworld (talk) 18:59, 19 December 2023 (UTC)

As for your accusation of “multiple reverts”, please note that I reverted two edits by IP because my edit was removed by IP twice. Thanks. --Dustfreeworld (talk) 19:03, 19 December 2023 (UTC)

I tend to agree with the IP editor that the video's connection to the article subject is too tenuous to be useful. Squeakachu (talk) 19:45, 19 December 2023 (UTC)

Please remember to keep a civil tone in these discussions, and refrain from personal attacks.

Your logic is still missing a step: you seem to assume that all roadwork globally contains slag, but your cited sources have not established that. 129.224.209.91 (talk) 05:38, 21 December 2023 (UTC)

Your reverts

As the order of the above posts were altered and I’m confused, I’m starting a new section. I didn’t reply to your post because I don’t want to escalate, but now you are reverting again, there seems to be no choice left.

OK, you agreed that roadworks in the US use slag.

Then the question is:

• Do roadworks in the U.S. use power tools or machineries that generate a large amount of dust?

• Or, do you mean roadworks in US only use hand tools?

• If roadworks in US DO generate dust, it doesn’t really matter where the video was taken. The video is used to illustrate that the material used in road construction can be turned into a large amount of fine dust easily. Are you disputing that?

But just to address to your specific concern:

• “The use of steel slag as an aggregate is considered a standard practice in many jurisdictions, with applications that include its use in granular base, embankments, engineered fill, highway shoulders, and hot mix asphalt pavement” https://www.fhwa.dot.gov/publications/research/infrastructure/structures/97148/ssa1.cfm

And I still don’t understand why I need to prove the sky is blue just because a user said they didn’t know it. Slag is widely used in Hong Kong’s construction sector as early as 2012. Anyway, here you go:

• Use of slag in public flats to cut carbon emissions, (SCMP)
  • (if anyone is interested, it probably means that any renovation or refurbishment work implemented at those flats at any time, and which will generate concrete dust, may release the potentially toxic slag ingredients to the air).

As for “keep a civil tone in these discussions, and refrain from personal attacks”, if it’s referring to your erroneous accusation of another Wikipedian in violation of 3RR (plus starting a discussion with their user name in title), I totally concur with that. And would be more than happy to see the other party striking out their PA text and apologize, instead of keep edit-warring. As the discussion is getting uncivil, I’m not sure if I would like to commit to this potential time sink anymore.

And I think you may want to review WP:SPA, WP:FIES and Slag#Construction. Thanks and regards, --Dustfreeworld (talk) 10:48, 2 January 2024 (UTC)

The video has almost no real relevance to the topic, and if it did, it does not add any useful information to the topic. From your user name, adding the video seems to be more motivated by activism (like advertising, you're not supposed to be doing that on Wikipedia). Re your question about tools in the US, the US requires water to be used when cutting concrete to prevent dust (I'm pretty sure it is the same in Canada, UK, Australia, and most EU countries). The video should be removed. — al-Shimoni (talk) 07:05, 8 February 2024 (UTC)

Hi there, please kindly note that my username is “Dustfreeworld”, but *not* “DustfreeworldIsGood”, “DustfreeworldIsBad” or “DustfreeworldIs???”. I don’t think the concern you mentioned is valid. Please AGF, thank you.

FYI, in the place where that video was taken, it is required that “water (or equivalent measures) to be used when cutting concrete to prevent dust” too. You may want to take a look at these media about dust emission in other parts of the world too:

• https://en.wikipedia.org/wiki/File:DustWorker.jpg
• https://en.wikipedia.org/wiki/File:Reducing_Dust_inside_Enclosed_Cabs.webm

I do agree that the text of the article isn’t clear enough. I’ve edited it. Please read it as well as the discussion above (which I believe there maybe misread /misunderstandings) again. I may not be able to come back to you very soon due to RL issues in case there are other concerns. The article needs expansion, but again, I don’t have time to do it for now. Thanks and best regards, --Dustfreeworld (talk) 08:49, 9 February 2024 (UTC)
