Abstract
Inventia se refera la un procedeu combinat de prelucrare a concentratelor complexe. Procedeul, conform inventiei, se utilizeaza în prima faza prin prajire, urmata de deplumbare integrala sau partiala a prajitului rezultat prin lesieere cu solutie de clorura de calciu, care dupa materialul rezultat, este fie prelucrat pirometalurgic pentru recuperarea fierului si zincului, fie lesiat cu solutie de H2SO4 astfel ca pH-ul final sa fie 1,5...2 sau 3,8...5,2 în functie de natura concentratului supus tratarii si de reactivii disponbili, folosindu-se la neutralizare ZnO rezultat din proces, iar pentru separarea cuprului solubilizat prin lesiere sulfurica, burete de fier rezultat din proces.
