Mineralogy and Cultural Heritage
CHIMIA, 2010 In recent years there has been an escalation in the number of mineralogical studies involving cultural heritage materials. A number of factors have contributed to this exponential growth, including the shrinking budgets in traditional research fields, which forced the expansion of applications of mineralogical methods to novel research areas.

The Canadian Journal of Chemical Engineering, EarlyView.Abstract This study proposes a novel, green, and sustainable method for synthesizing magnetic iron oxides from metallurgical copper slag (CS), leveraging its iron content as a valuable resource. Iron was extracted via acid leaching using edible citric acid (ECA), forming a citrate–iron complex (CSL), which was subsequently thermally decomposed at 300°C
