Hard to believe I found that structural steel is 93% scrap.

Metallurgy is just a specialized kind of chemistry. ALL our metals are recyclable, and are made out of elements like iron (Fe), Magnesium (Mg), ... This list goes on. Pretty much everything that is metal is yellow on this chart. Or orange.

What determines whether metal gets turned into something useful like structural steel is the economics of the starting materials. Slag tends to be discarded because it costs too much to recover the useful metal out, or the contaminates are just too hard to separate.
 
A lot of good info on how the countries make their steel. It seems like Japan has got it figured out. My Sugi bars, Silkey blades and poles are second to none. How does Japan do it?

At over $90 per blade, Silky can afford to use the very best metal they can find.

I will assure you no steel plant that I have ever seen discards slag. That would be like saying coal burning power plants discard cinders and rock quarries discard fines.
 
They use copper slag as a blast media. It doesn't go to waste.

Well then! I guess you need to look around a little more. Here's some fields filled with metal slag:

All from Sheffield Steel. Ever hear of them?

Most of this area is also slag-field, but they built other metal plants on top of it:

I don't know how deep they were filled up from the old metal plant, but they are as high as the nearby levies.
 
Bill! You made a statement. YOU should be backing it up.

Besides, Coal burning facilities are well known for their ash deposits.

Geez! It took me a whole 20 seconds to get an answer.

"Coal ash is one of the largest types of industrial waste generated in the United States. According to the American Coal Ash Association's Coal Combustion Product Production & Use Survey Report, nearly 130 million tons of coal ash was generated in 2014."
 
Yeah, right.


Just look for some videos. Use any search engine, seek out "metal slag being dumped".

Great...................now go do the research to find out what happens next.

Also as usual you failed to read what I wrote when I clearly said......................

Have you personally seen a steel plant plant discarding slag or just a online video? We have plants here and I have spent many hours growing up spreading slag. In the morning I can go over and pick up a handful of slag we have had for 35 plus years.

Please directly quote what statement you would like me to back up.

Do you really think I didn't read your inane statement with your escape clause built in? I guess you didn't read very well when I answered this::
I will assure you no steel plant that I have ever seen

With this:
Well then! I guess you need to look around a little more.
