recommendations! Published in 2025 at "Asia-Pacific Journal of Chemical Engineering"

DOI: 10.1002/apj.70028

Abstract: Dolomite is the predominant calcium‐bearing gangue mineral in low‐grade magnesite ores. The structural isomorphism and compositional similarity between dolomite and magnesite create significant challenges in their selective flotation separation. This work employed sodium dodecyl sulfate… read more here.
