Abstract:The constraints on the metallurgical industry in terms of resource transformation, energy consumption and environmental protection are becoming increasingly severe, and there is an urgent need to upgrade metallurgical processes to enable environmentally friendly, energy-saving, value-added production. Reference is an important way of innovation. On the one hand, imitation of existing metallurgical processes to develop new metallurgical technologies is undoubtedly the most direct means, especially the industrialized process provides a multi-dimensional reference in the "science-technology-engineering" aspect. On the other hand, the interdisciplinarity is more likely to produce disruptive technologies for metallurgy, such as geochemistry, mineral processing, and electrochemistry (batteries).
