Waste from mining and processing, including residual minerals and chemicals, can also contaminate water in nearby communities. Current processes for extracting lithium — a critical mineral used in both electric vehicle (EV) batteries and solar panels — are particularly water-intensive. Take the "lithium triangle" in South America.

The mining process is used to separate rock or ore from surrounding rock. There are four main mining methods: underground, open surface (pit), placer, and in-situ mining. The method used depends on the type of mineral resource that is mined, its location beneath the surface, and whether the resource is worth enough money to justify extracting it.
