Processability of complex, low-grade nickel (Ni) laterite ores via heap leaching is very limited due to some intractable geotechnical and hydrological challenges such as poor heap porosity/permeability and structural stability. This work presents some investigations on laboratory batch drum agglomeration and continuous column leaching behaviour of saprolitic (SAP) and goethitic (G) Ni laterite ores as part of the quest for an effective pre-treatment process for enhanced heap leaching. As a focus, the effect of ore mineralogy/chemistry on the agglomeration and column leaching behaviour of -2 mm (crushed from -15 mm run-of-mine) G and SAP Ni laterite ores was examined. To produce -5–40 mm agglomerates in <15 min, the SAP ore provided a higher H2SO4 (30 wt.%) blend dosage compared with the G ore, although both ores displayed substantially similar, coalescence-controlled agglomeration mechanism. The findings show the relevance of agglomeration and column leaching tests for providing useful information for plant designing and optimization of Ni laterite heap leaching operations.
