ANALYSIS ANALYSIS ARTICLE VOL. 6(22), 2020 SCIENCE. Crushing was done first by reducing the sizes of the galena (test ore) from boulders to 10 mm and charged into Denver laboratory jaw crusher (Model DXPC), followed by Denver cone crusher (Model DV 24355) and finally into the Endecott roll crusher (Model EQM -50 L) and unto sieve of aperture 1180 µm
