Mine tailings are presumably just the rock you dug out minus one of the component minerals. Is it fine to stuff it back into unproductive mineshafts, or does the increased drainage from the tunnels and the fracturing of the rock make that problematic? As for the superfund apartments, I wonder - if they did the cleanup job properly, the new apartments could plausibly be better than the properties downwind outside the cleanup area, and you may get good deal just because it scares off some buyers. On the other hand, that's a big if.

Yeah that's all mine tailing are, just rocks minus one element. Holy poo poo get your life together man.

I think an argument against putting the tailings back is that it's an uneccesary cost, and since there's no legislation against just dumping it on open ground whilst laughing and twirling your moustache that's what people do.

Often times the tailings also include traces of nasty stuff used in the process of extracting the desired product - for example gold mine tailings having a bunch of mercury and cyanide.

Right, that's kind of important. I was wondering more about the minerals where you can do mechanical separation (first), so you have "clean" tailings - those can still leech all sorts of things you don't want in your water, but on the other hand they're literally just rocks out of the ground. It's kind of a stupid question, but I was honestly just wondering if putting them back in the ground would be good enough, or if the increased water permeability makes that a bad enough idea that it may be better to keep them in a pile you can monitor.

It's a good job that gigantic piles of mined material are completely safe and have never in history slid down a hillside and demolished, say, a school

Yeah, instead of being encased in hard rock they're now mostly powder.

A video/photo report of the lifting and moving of an abandoned, sunken ship from the harbour of Kotka, Finland. Google Translate should work (except I noticed it translates 23 metres into... 23 feet, I hope NASA doesn't use Google) https://translate.google.com/translate?sl=fi&tl=en&u=https://yle.fi/uutiset/3-11868553 https://yle.fi/uutiset/3-11868553 Posting this because a) it's interesting and b) I'm not convinced all these people working on the pier and the ship are wearing all required PPE.

They say if you can't properly sink some bolts into the floor for your safe, you should attach it to something that wont fit out the door.

The thermostat does nothing. It's there, but it does absolutely nothing. I used to always keep a window open in my apartments. Thermostat is supposed to control a zone valve that opens or closes and controls the flow of hot water through the radiator. It's pretty common for the actuators on the valves to fail. Anybody ever take a look at it?

This isn't just from the milling process, specifically in gold mining, cyanide is also deliberately added after the fine tailings have been stored to leach out the last few tenths of a gram per ton from them.  The two rectangles are ~80m high tailings piles that have cyanide sprayed over the top of them by a sprinkler system, which binds to gold ions in the fine tailings and makes them water soluble. The leaching ponds can be seen to the northeast of the big pile and a complex of ponds to the northwest of the longer one.
