Mineral resources and geo-engineering
Metals used in everyday life are produced from ores occurring in the Earth’s crust. Geological processes are known to concentrate minerals to form ores of economic value. Mineral processing engineers concentrate these ores by mechanical and physico-chemical methods while the extractive metallurgist extracts the metals by chemical means.

متن کاملRanking geo-engineering schemes
P ropelling aerosols into the upper atmosphere or pumping carbon dioxide into the deep ocean are just two schemes that have been proposed to repair the Earth’s climate through geo-engineering1 (see Box 1). In the absence of adequate reductions in anthropogenic CO2 emissions, geo-engineering has been put forward as the only remaining option that might fix our rapidly changing climate2. Because s...
متن کاملObservation-Driven Geo-Ontology Engineering
Big Data, Linked Data, Smart Dust, Digital Earth, and e-Science are just some of the names for research trends that surfaced over the last years. While all of them address different visions and needs, they share a common theme: How do we manage massive amounts of heterogeneous data, derive knowledge out of them instead of drowning in information, and how do we make our findings reproducible and...
متن کاملGeo-engineering: a curse or a blessing?
SUMMARY In recent years, geo-engineering has been suggested as a viable strategy in dealing with climate change, the main indicator of what has become known as 'the Anthropocene'. In this paper, I investigate the effects of geo-engineering in terms of freedom – not the only but perhaps the most important measure of moral and political desirability. Is geo-engineering a curse or a blessing, a po...
