Big Wind's Dirty Little Secret: Toxic Lakes and ...

The environmental impacts of mining a metal ore are determined partly by the ore's percentage of metal content, or grade. The more accessible higher-grade ores are usually exploited first. Mining lower-grade ores takes more money, energy, water, and other resources, and leads to more land disruption, mining waste, and pollution.
