Abstract:
Manganese ore fines generated during manganese production are either partially recycled as agglomerates using binders, or stored, leading to pollution, and negative environmental impacts due to landfilling. Fines have for long been considered as environmental unfriendly, loss if not recycled and stage threats in the metallurgical industry if not taken care of. [..]

Abstract:
Quarry dust and concrete recycling dust, generated as solid waste during rock and concrete crushing operations, poses a significant environmental challenge. Rich in SiO₂, these fine-grained materials hold potential as fluxing agents in pyrometallurgical processes, yet their metallurgical applications remain underexplored due to the complexity of such waste streams.
