During mining operations, and after the site has been closed, managers can ensure that their business impact on the Heart of Borneo is minimized. Company case studies show that this is achievable.
Managing mining operations
1. Reduce mercury use
Mercury is a metal that can be highly toxic to both humans and wildlife. Mercury use in gold mining is banned in both Malaysia and Indonesia, however its use persists.In Central Kalimantan, over 50 tons of mercury is estimated to be emitted into the environment annually, in one location alone.
There are efforts to help small-scale miners reduce the negative health impacts from mercury use, and potentially find alternative revenue streams.
next steps
- Read about the the Global Mercury Project, which is working in Kalimantan to reduce the use of mercury and provide miners with mercury recycling technology
- Read about Tambuhak Sinta Foundation, which works with government, NGOs and donor agencies in Kalimantan
2. Rehabilitate mining sites
Mining activities only require the temporary use of land and once the valuable resources have been extracted it is vital that the area is adequately restored to its previous state.- Mine rehabilitation plans should be drawn-up before mining activities begin, and approved for each mine as part of the EIA
- Plans for the reclamation and rehabilitation of mines need to include provisions for pre-mining assessments, storage of sediment and top soils during mining activities, and a strategy to return removed soil, and replant the area to encourage natural regeneration.
