REGENERATION METHOD OF DECOPPERING SOLUTION FROM BACTERIAL LEACHING INSTALLATION

REGENERATION METHOD OF DECOPPERING SOLUTION FROM BACTERIAL LEACHING INSTALLATION

Inventia se refera la un procedeu de regenerare a solutiei decuprate din instalatiile de lesiere bacteriana a minereurilor cuprifere, caracterizat prin aceea ca solutia decuprata prin cementare cu span de fier, care contine pîna la 25 g/l Fe exponent 2+, se trateaza cu un amestec de aer cu ozon, car...

description Inventia se refera la un procedeu de regenerare a solutiei decuprate din instalatiile de lesiere bacteriana a minereurilor cuprifere, caracterizat prin aceea ca solutia decuprata prin cementare cu span de fier, care contine pîna la 25 g/l Fe exponent 2+, se trateaza cu un amestec de aer cu ozon, care, în prezenta bacteriilor Tiobacillus ferroxidans, accelereaza viteza de oxidare a Fe exponent 2+ la Fe exponent 3+, iar hidroxidul feric rezultat în urma hidrolizei Fe exponent 3+ se separa din sistem prin flotare, cu utilizarea ca colector anionic a lauril-sulfatului de sodiu, iar solutia limpede se trimite în cultivatorul de bacterii pentru atingerea concentratiei optime în procesul de lesiere bacteriana.
