  • Only a stone's throw from Salt Lake City lies the world's deepest mine - Rio Tinto Kennecott. Hardworking miners have extracted copper, silver, gold, and other critical resources here for over a century.
    Not only do they mine incredible amounts of ore here using shovels and trucks, but it's also America's only integrated copper mining operation. This means they start with rock and end with 99.9% pure copper, all in the same place!
    If you use electricity, you use copper. It doesn't get more essential!
    To learn more about the operation, check out the website linked below:

    Fun fact, they actually bought the town of Bingham right next to it, and completely covered the houses in waste ore. Another fun fact, they actually have no idea where a lot of the underground sections are from back in the day, so sometimes when they drill or blast they blow straight into an old shaft and send an rc car with a gps and camera into it to map the surrounding area. I’d say it’s definitely the coolest place I’ve ever worked haha

    I could have watched 3 hours on this mine. The thing most people dont know about copper is that most deposits are like less than 5% copper. So when you say copper ore, it makes you think its 30---70% copper, but no, its nowhere close to that.

    • @AaronWitt

    Thank you Mr. Mines 😊❤😊 for going to the BIGGEST Mine and one YES went to the observation ( visiting) overlook. Those BIG haul trucks look so small standing overlooking the vast open pit. If you ever visit Sail Lake City please go visit this amazing site. 😊 It is well worth your time. It looks so different than when I went just a few years ago. The Huge CAT graders working in threes keeping the haul road smooth 😊 these graders are the biggest ones CAT makes. There was a tour bus at gift shop at overlook. The works said the riders in the bus were students from an engineering school who were getting access like you to mile floor and work areas. There is an operator training building for new and experienced operators to practice with a small remote control P&H shovel with control set up just like a real Shovel. To upgrade their skills. These students were going to get to operate that great teaching aid. 😊 There is a pumping station at bottom to STOP the ground water from filling the mine, saw a big CAT excavator digging and opening these basically rivers that pour water through the bank above and to the side of haul Roads. As soon as the "BLAST" went off, the Huge CAT Dozer started "Ripping" the blast area. I can't stress it enough if you have ever wanted to SEE a big open pit mine, see the giant shovel haul trucks and the other huge equipment actually working a cut.😊 Go visit this mine. Even though we were in Salt Lake to go to a truck convention and driving & Backing up semi's competition see the BYU big church school campus. See the Island in the middle of the great Salt lake. This trip to mine was my best and favorite 😊❤😊 part of trip there. I will go again. A big thanks again for doing video on this wonder of earth 🌍 works.
    They do get a LOT of GOLD out of mine besides just their main copper ⛏️

    SAG mills DO have grinding balls in them "SAG is an acronym for semi-autogenous grinding. SAG mills are autogenous mills that also use grinding balls like a ball mill." Autogenous or "auto" mills do NOT have grinding balls in them and use rock on rock action to grind up the ore

    I visited the Bingham mine about 25 years ago. The visitor's center was in the pit itself and you could watch the as they hauled ore to the crusher. You had to be careful as you drove on the access road to the visitor's center as you reached a point where haul trucks crossed the access road. I have no idea how much the set up has changed since.

    This mine is the largest producer of the element scandium. Scandium while being relatively common has no known deposits so one source of broken rock is as good as another and this is the the largest pile of broken rock in the world. While being common the lack of scandium deposits means that on a per gram basis scandium is more valuable than gold and this place makes the most.

    I just came here to say pennies aren't copper anymore. They stopped making pennies out of copper in 1982. If a penny was made out of copper today it'd be worth about 3 cents. Now you can argue that the mint makes up for that shortfall when they print twenty dollar bills but that's not how they see it. The copper plating is pretty thin so you can scrape it off and see the base metal that's inside of a penny. It's zinc.
