Froth flotation is widely used to recover spodumene, a key lithium-bearing mineral. However, the recovery efficiency of fine spodumene particles (<30 um) remains a significant challenge due to their low mass and poor collision efficiency with air bubbles. conventional flotation methods often struggle to effectively separate these fines, leading to significant lithium losses in processing operations. this study explores a selective aggregation-flotation strategy to improve fine spodumene recovery. calcium ions (ca2+) are introduced to selectively activate spodumene surfaces, enhancing polymer and collector adsorption. anionic polyacrylamide (pam) flocculants are then applied to induce selective aggregation, forming larger spodumene aggregates (>50 um) while quartz remains unaggregated. These larger aggregates exhibit improved flotation kinetics and separation efficiency. This method significantly improves the recovery of fine spodumene and offers a scalable and sustainable solution for lithium beneficiation. The findings contribute to optimising critical mineral processing and support the industry's transition toward more efficient and responsible resource utilisation.
