Algae and mining: A new frontier in sustainable site rehabilitation

Algae might seem an unlikely candidate to help transform Australia’s post-mining landscapes, but a new CSIRO -led project suggests these tiny aquatic organisms could provide sustainable futures for mine sites, surrounding ecosystems, and local communities. Looking down the microscope at the microalgae Nannochloropsis Australia’s mining sector is approaching a crossroads—where economic legacy and environmental responsibility must find common ground. A new CSIRO -led study, supported by the Cooperative Research Centre for Transformations in Mining Economies (CRC TiME), suggests that one of the most promising bridges between these imperatives may come from an unexpected source: algae. Though small in stature, algae are emerging as giants in their potential to transform post-mining landscapes. The study, developed in partnership with the University of Queensland and Murdoch University , proposes that algae-based technologies could reduce mining’s environmental footprint while seeding new...

Mining drives socio-economic development in Laos

Mining is contributing to local and national development outcomes in Laos, according to a new report by the International Council on Mining and Metals (ICMM). 'Utilizing mining and mineral resources to foster the sustainable development of the Lao PDR' found that mining has come to represent 80% of foreign direct investment in this mineral rich country.

The mining industry is a significant contributor to the country's economy, providing 45% of total exports, 12% of government revenues and 10% of national income. These benefits have been complemented at the local level by stimulating markets and enhancing incomes.

The study also reveals key challenges, including ensuring that public financial management is predictable and transparent, and insulating the economy from fluctuating international commodity prices. The research identifies a need to develop a supportive enabling environment, in which local businesses can seize opportunities in the mine supply chain. Diversity and gender issues were also recognized as challenges at the local level.

The Lao PDR report is ICMM’s fifth country case study examining the social and economic impacts of mining. It was sponsored by ICMM's first Chinese member company, MMG, and the government of Lao PDR has broadly accepted all the findings of the report. It is jointly published by ICMM and the Ministry of Energy and Mines as well as the Ministry of Planning and Investment.
