The natural diamond mining industry has evolved significantly in its approach to environmental stewardship. Today, many major mining companies follow strict regulations and implement programs aimed at protecting, minimising harm to, and rehabilitating the environment. Here’s how the industry typically addresses these responsibilities:
1. Environmental Impact Assessments (EIA)
Before any mining begins, companies conduct detailed Environmental and Social Impact Assessments to evaluate potential effects on ecosystems, water, air quality and local communities. These assessments are crucial for:
- Planning mitigation strategies
- Obtaining government approvals
- Engaging stakeholders and indigenous communities
2. Land Use and Biodiversity Protection
Diamond miners often work in remote or ecologically sensitive areas, so protecting local biodiversity is a key concern. Efforts include:
- Avoiding mining in designated protected areas
- Creating biodiversity action plans
- Relocating flora and fauna where feasible
- Establishing wildlife corridors and sanctuaries
Example: De Beers’ Diamond Route initiative preserves and manages over 200,000 hectares of land for conservation in southern Africa.
3. Water Management
Diamond mining can require substantial water use, especially in alluvial and kimberlite pipe mining. Companies implement:
- Closed-loop water recycling systems
- Water quality monitoring and treatment before discharge
- Minimisation of water withdrawal from nearby lakes or rivers
- Strategies to prevent acid rock drainage and contamination
4. Energy Use and Emissions Reduction
To reduce their carbon footprint, diamond mining companies are:
- Transitioning to renewable energy sources (solar, wind, etc.)
- Implementing energy-efficient technologies and electrified mining fleets
- Participating in carbon offset programs
- Tracking and disclosing emissions as part of sustainability reporting
5. Waste Management and Pollution Control
Modern diamond mines are required to:
- Properly store and contain waste rock and tailings
- Use lined tailings dams and dust suppression techniques
- Monitor air and soil quality continuously
- Prevent spillage of fuels and chemicals through strict protocols
6. Progressive Rehabilitation
Even while a mine is still operational, many companies start progressive rehabilitation, including:
- Re-contouring and stabilising land
- Replacing topsoil
- Replanting native vegetation
- Reintroducing wildlife when safe
After mine closure, full rehabilitation plans are carried out, often converting former mines into wildlife reserves, parks, or community-use areas.
7. Independent Audits and Certification
Many diamond mines operate under environmental standards verified by:
- ISO 14001 (Environmental Management Systems)
- Responsible Jewellery Council (RJC) certification
- Initiatives for Responsible Mining Assurance (IRMA)
- Compliance with national and local mining laws
8. Community and Indigenous Involvement
Environmental programs increasingly involve local and indigenous communities, who contribute traditional ecological knowledge and help monitor impacts.
In Summary:
Natural diamond mining companies today emphasise:
- Prevention: through planning and smart design
- Protection: via conservation and pollution control
- Restoration: through land rehabilitation and biodiversity support
While no form of mining is impact-free, the industry’s leading operators are making substantial efforts to align with global sustainability goals.
