Phase composition of metallurgical zinc and lead slags
Journal Title: Civil and Environmental Engineering Reports - Year 2013, Vol 1, Issue 11
Abstract
Slags formed in the “Miasteczko Śląskie” Zinc Smelting Plant process contain substantial amounts of heavy metals such as Pb, Zn, Cd, Cu. In hypergenic environment this elements may occur in stable or unstable phase. Environmental conditions and the forms of occurrence of elements decide about metals stability and mobility. On the basis of laboratory, microscopic and modeling studies it was found that the main phase present in slags from the current production of the shaft furnace is fayalite, which is unstable in EhpH wide range in water and soil environment of the surroundings of HC “Miasteczko Śląskie”.<br/><br/>
