DOI: 10.3390/molecules30204076
Abstract: Serpentinite rocks and their processing waste represent a valuable source of magnesium and silicon; however, their complex composition complicates the efficient recovery of individual components. This study investigates the combined acid–alkali processing of serpentinite waste… read more here.
