The global significance of artisanal and small-scale mining certain mineral commodities implies the need for evaluating this production component as a potential long-term source supply, in conjunction with from industrial operations. tantalum sector is an important pioneer regard, ‘coltan’ ore – mainly extracted Democratic Republic Congo (DRC) Rwanda has represented world's major over past decade. lack economic data pertaining to coltan extraction trade Africa's Great Lakes region adds...
Abstract Mining activities have always raised environmental and social concerns due to their impact on natural resources people. During the last decade, stakeholder base expected respond these sustainability has broadened from directly involved parties a range of indirect stakeholders along downstream mineral value chain. These variably engage in reporting, supplier risk assessments, exercising supply chain diligence, third party assurance, corporate responsibility measures. This trend...
The mining industry provides the raw materials needed for economic and social development. At same time, it is a large user and, occasionally, polluter of shared water resources that form foundation healthy ecosystems dignified human life. Realizing sustainable use in operations requires meaningful information on mine site-water interactions allows stakeholders to build opinions, make sustainability-oriented decisions procurement, permitting or investment, hold companies accountable their...
Environmental and social issues are increasingly recognized as a main business risk in the mining sector therefore threat for raw material supply security. Criticality assessment methods seek to determine based on certain indicators. These indicators, measuring different governance aspects producing countries, often used indicate general framework under which production takes place. While typically employed reflect country's political economic stability, recent criticality assessments have...

An increasing number of methods have been developed for guiding water risk assessments in different commodity sectors. With being a key sustainability challenge mining operations, these may help investors and downstream industries to respond rising demands responsible sourcing investment practices. However, their fundamental predictive accuracy the sector needs be resolved. This study tests ability three assessment adequately reflect water-related risks operation based on case approach six...
We present a data set on the geochemical and isotopic composition of mineralized porphyry intrusions, se- riate arc volcanic formations spatially associated with late Oligocene to Miocene, porphyry- related ore deposits in Ecuador. Our aim is constrain petrogenetic evolution these magmas, evaluate geodynamic tectonic impact factors magmatism, explore metallogenic signifi- cance parameters. distinguish four groups investigated magmatic centers, indicating dif- ferent paths low- high-pressure...
