“…Fosso-Kankeu et al (2011) tested the biological recovery of nickel from tailing. In Germany, Kamradt et al (2012) studied the recovery of Cu and Ag. A recently started project in central Sweden identified many mineralisations and deposits in this region, the majority of them being associated with mine dumps with high average rare earth elements contents (Högdahl et al, 2012).…”

Raw materials are essential for the sustainable functioning of modern societies. Access to and affordability of mineral raw materials are crucial for the sound functioning of the European Union's economy. The increasing demand for raw materials raises growing concerns regarding mineral resources and especially metals availability. Furthermore, many metals, metalloids or rare earth elements that had no application in the past are now used for the manufacture of high added-value products, especially in the domain of new and green technologies. Many of them are by-products of base metals production, and their reserves are very limited. Therefore a list of strategic and critical materials was established by the European Commission in 2010. Following the rich mining history of France, there are currently some 300 mineral deposits mined or significantly explored. These are the source of large quantities of 'tailings' (gangue, processing waste resulting from concentration or hydrometallurgical treatment, slag, heap). The European Directive 2006/21/EC of 15 March 2006 on the management of waste from extractive industries oversees the permit conditions, storage, monitoring and control of mining waste to ensure the protection of human health and the environment. The member states have to carry out and periodically update an inventory of closed waste facilities that cause or have the potential to cause a serious threat to human health or the environment. Moreover, the directive encourages the recovery of extractive waste by means of recycling, reuse or reclamation. Following this, an inventory was finalised in France in 2012 in which 2,100 metallic and 1,300 coal tailings were identified and prioritised according to their potential impacts on groundwaters, surface waters, soils and human health. Among these, 53 sites with major environmental issues were listed. These sites are and will be the subject of specific actions (environmental and sanitary studies, works of rehabilitation) in order to reduce their long-term impact on both human health and environment. While metallic elements present in the tailings are by nature nondegradable, these actions require long-term approaches. The paper focuses on one of these sites, former Pb-Ag mines, where operations have led to the production of 200,000 m 3 of mining waste. A French Geological Survey (BRGM) rehabilitation programme, based on environmental studies, was designed to stop additional tailings erosion towards the river and the surrounding areas and to avoid any contacts between the contaminated materials and the population. Metals recovery could be envisaged to mitigate the remediation cost. https://papers.acg.uwa.edu.au/p/1352_48_Bellenfant/ Reprocessing of mining waste: combining environmental management and metal recovery?

“…The main drawback of these methods is that they are not able to treat the AMD for selective metal recovery; instead, a mixture of organic matter and metal sulfides is produced, which itself represent a hazardous waste material, which has to be managed in a proper way. Thus, new research goes into the selective recovery of the metals from industrial waste solutions like AMD, in order to recover as much economic values as possible (Hallberg 2010;Kamradt et al 2012).…”

“…Recently, unconventional deposits of minerals have grown in commercial interest as alternative mineral supply options. On land, waste from mining and processing is considered for potential reprocessing with new technology to extract metal [28,29]. Offshore, such unconventional ores include those found on the deep seabed, which have been an exploration target for decades but only recently come close to extraction, led by Nautilus Minerals in Papua New Guinea [30].…”

Environmental Implications of Resource Security Strategies for Critical Minerals: A Case Study of Copper in Japan

2018

View full text Add to dashboard Cite

In the assessment of critical minerals, environmental impacts have been a focus of a number of methodologies. In the case of resource security for critical minerals, there are a variety of potential strategies that might be used to reduce criticality from the supply risk perspective, but the environmental consequences of these strategies need to be evaluated. Japan is a country with a heavy dependence on imported materials, and thus has examined various alternative resource supply strategies to improve resource security. This study examines these alternative strategies and evaluates the consequential environmental implications, focusing on the domestic impacts in Japan. Utilization of deep ocean mining and end-of-life home appliance recycling are examined as alternatives against the conventional, import-oriented process. From the obtained results, deep ocean mining, providing 30% of domestic copper demand with the remainder supplied from recycling, is the current optimal solution with regards to the environmental impact.
