Water pollution
Acid mine drainage
Mining waste
Tailings & waste rock
Tailings dams

Decades after closure
How the major economies regulate mining
China
Green Mine Construction Program
National Green Mine standards
Ecological-restoration standards (2024)
Restoration-plan requirements
Strong restoration focus; enforcement varies across regions.
European Union
European Green Deal
8th Environment Action Programme (8th EAP)
Critical Raw Materials Act (CRMA)
Directives: Mining Waste · EIA · Water Framework · Habitats · Birds
Most comprehensive — but pressure for new domestic mining will test these standards.
United States
Surface Mining Control & Reclamation Act (SMCRA)
Abandoned Mine Land Program (AML)
EPA National Hardrock Mining Framework
Clean Water Act
National Environmental Policy Act (NEPA)
Strong cleanup record; rules fragmented and politically driven.
Developing countries
Impacts are often greater, and the gap is usually enforcement, not rules — common problems include water pollution, deforestation, poor waste handling and widespread informal small-scale mining. Mercury: artisanal gold mining is among the world's largest sources of mercury pollution.
