and Process waters

Fields of application

Passive and active treatment of acid, neutral and basic mining drainage, acidity, metals and metalloids;

Development of treatment processes for nitrogen compounds and derivatives (ammonia, nitrates, nitrites, thiocyanates and cyanates) by physical, membrane, physicochemical, biological and electrochemical approaches;

Sequential extraction and TCLP, SPLP, CTU-9 and CTU-10 leachate tests;

Development of innovative processes for valorization of mine tailing and extraction of valuable metals through bio-oxidation, bio-leaching and bio-cyanidation;

Assessment of new approaches of recirculation and regeneration of cyanides from the mine effluent;

Sampling and environmental characterization of mine residues (solids and liquids);

Passive and active treatment of metals and metalloids (examples: arsenic, copper, selenium, manganese, nickel, zinc, antimony and chrome);
