recommendations! Published in 2017 at "Applied Geochemistry"

DOI: 10.1016/j.apgeochem.2017.09.007

Abstract: Abstract Production of sulfuric acid by roasting of pyrite (Fe sulfide) produces a Fe rich waste product, pyrite cinder (or pyrite ash), which often contains high levels of trace metals such as Zn and Pb.… read more here.

DOI: 10.1038/s41598-024-83586-y

Abstract: Pyrite cinder could release more heat to improve he acid decomposition reaction of ilmenite, lower concentrations of sulfuric acid, increase the amount of TiO2 waste acid reused, reduce titanium gypsum emissions, and promote the green… read more here.

DOI: 10.3390/met9080911

Abstract: This study proposes a cleaner lead-acid battery (LAB) paste and pyrite cinder (PyC) recycling method without excessive generation of SO2. PyCs were employed as sulfur-fixing reagents to conserve sulfur as condensed sulfides, which prevented SO2… read more here.

DOI: 10.3390/min14070652

Abstract: Industrial activities have historically generated significant quantities of by-products, including pyrite cinders, a residue produced during the synthesis of sulphuric acid. This study presents a multidisciplinary approach to characterise an abandoned pyrite cinder deposit. Combining… read more here.
