Reasons to use coal? Here you are.
Slag is from refining, Mining wastes are called tailings.
Slag is where its found along with the tailings..mostly the slag. My Mistake. Is that ok with you or do you have a big problem?
It all comes out of the Earth so it’s all good.
BTW. In copper mining, like up in the Copper Country of MI, its also called stamp sands.
“Is that ok with you or do you have a big problem?”
I have NO problem but it seems you have a BIG problem when you realize you made a mistake.
Get over it. We all make mistakes.
“BTW. In copper mining, like up in the Copper Country of MI, its also called stamp sands.”
I had to look that one up. Stamp sands is a type of sand which that is mined.
Those mine tailings are composed of stamp sands.
Dude slag comes from coal fired plants too. I personally know of large coal ash pits and coal slag piles from tapping bottom slag out of positive pressure boilers. Better study up a little. Every coal plant operator worth a shit knows this. B&W, ABB, Foster Wheeler and others all burnt coal. Still do. I’ve operated one or two of each. Just saying.
Alberta Oilsands would have, likely, billions in rare earth metals as well.
I don’t recall all the numbers, but coal ash is collected at power stations and piled and kept above gound for several years. After that, it is returned to the pits the coal was extracted from. So, the cycle now would be to take the ash, extract important minerals, then bury it from where it was dug from. I can’t think of anything easier and cheaper than having the ash sitting in giant piles for the taking. AMAZING!
No doubt.
“Stamp sands is a type of sand which that is mined.”
No it aint.
Its the material left after the processing of the ore at a stamp mill.
Guess we all make mistakes huh?
Actually fly ash is generally slurried out to ash pits wet. Ash tends to fly around in the wind. You wash it out in a pit to make sure it doesn’t blow around over the local people living close by. We had a dust accident on one of our bag houses that blew offsite and a gentleman called bitching accusing us of ruining his barbecue and turning his wieners ( hotdogs for those in Rio Linda) green. I don’t know of any plant that stored fly ash exposed to wind in a pile. It goes out wet and gets covered.
How much is still left behind at those plants. Or did they haul it away totally?
I know one other on here says they put it back into the mines but there must be some huge piles left around no?
Fire them dam coal plants back up!
I recall reading in years past that some coal-fueled power plants stored their fly ash in ponds and some of these ponds were breached during storms resulting in spillage into nearby streams causing toxicity problems (don’t know if the toxins are heavy metals, organic combustion residues, or both). Expensive to clean up. Would be wonderful if a better use could be found.
Almost every mineral known to man is in coal ash. It’s just a matter of concentrations and cost of extraction.
The whole rare earths thing is only a problem because of massive artificial demand for stupid electric cars.
Once that disappears and demand is on a more realistic level for batteries and magnets, processing coal plant ash should generate enough to avoid massive imports.
I dunno about coal ash but I do know that waste from copper is toxic.
And up at the Keweenaw they dumped it into the lake. For years and years.
The point is here, they can build those coal fired generation plants and produce electricity, and take the ash and recover rare earth minerals from it.
According to the study, it appears the first step is done simply by the burning of the coal.
So, as you say, the next step is getting it out from the ash.
Remember in Obastards term the feds made that guy dig that plug out from that mine at Silverton CO?
Even after a mining engineer told them NOT TO MESS WITH IT?
I personally know that there were 3 coal pits being mined in the ground above Craig Colorado that the coal was dug and fed into three coal plants and the ash was put back in the holes the coal came from far as I know the ash is still there. I’m not sure what the Jim Bridge plant in Wyoming is doing with theirs. There’s a coal field in eastern Wyoming north of Cheyenne that was digging coal and burning it. Where the ash went I don’t know. I know I breathed enough fly ask and coal dust to make the poor coal miners shake their heads. Coal can be used safely and generate a lot of power, getting rare earth minerals too would be great. The plants mentioned above have or are being mothballed like our nuke plants. It dumbasses in DC that’s killing our country and idiots keep voting for them. Regards
