The goal of this research is to build environmental profiles for metals production from cradle to gate. The primary focus on metals is precious and rare earth metals. The result of this research might aid to decrease their environmental impacts, lead to better cleaner production, and enhancements of production technologies. It offers a scientific baseline on their discharges to air, soil, and water as well their contribution to environmental problems such acidification, human toxicity, freshwater aquatic system, and climate change. Project updates are available ResearchGate.
