> metal found in finite supplies
It averages about 25 parts per million in the Earth's crust, a bit more common than lithium at 20 ppm. Gold is 4 parts per billion yet no one seems to be predicting the end of gold supplies.
i suspect that ordinary price signals will drive better utilization, newer chemistries, political will to recycle more, etc.
- esturk 8y agoThat wasn't what the article said. If you truncate sentences in both directions to make a distorted point, you might as well stop. The rest of the sentence reads: > ... cobalt, a metal found in finite supplies and concentrated in one of the globe's more precarious countries. Notice how it reads differently.
