Agglomeration drums, also known as agglomerators, work by agglomerating the ore fines into rounded, more uniform pellets. This creates a more efficient leach, because round pellets allow more spaces between pellets for more even permeability. Agglomeration drums also provide an opportunity for pre mixing the leaching solution with the ore, to
