The present paper is focused on depollution techniques representative for mining and non-ferrous metallurgy, which will assure a radically changed technological concept for a clean, safe and eco-efficient production, leading to sustainable development industry. At the same time, our works propose the implementation in the mining and metallurgical sector of unconventional processes through innovative techniques that lead to processes intensification, reduction of energy consumption, decrease of carbon footprint, by...

Historical ore exploitations generated mining waste with useful metal content, near Baia Mare, Romania. Central Flotation Pond (CFP) represents a secondary resource, but also a risk factor of pollution for the environment: groundwater, surface water, soil, air. CFP was inventoried by the Permanent Secretariat of the International Commission for the Protection of Danube River (ICPDR) as high risks spot in Romania with immediate effects on Somes-Tisa sub-basin, due to the content of dangerous substances: cyanide, he...
