The agglomeration behaviour of selected model clay (kaolinite) and oxide (hematite and quartz) minerals which constitute the predominant host gangue phases of typical complex, low-grade laterite ores (e.g., nickel laterite) is investigated. Fundamental knowledge and understanding of the agglomeration mechanisms and kinetics that are essential for producing robust real ore granules which are pivotal to heap leaching processes are gleaned. Isothermal, batch agglomeration involving 30 % w/w H2SO4 solution as binder was employed for the study. Granules of sizes between 5 – 40 mm with differing roughness and morphologies were produced in 8-14 min. The results showed feed characteristics (mineralogy and primary particle size distribution) and binder content dependent agglomeration behaviour. The clay mineral displayed slow nucleation and growth agglomeration behaviour whilst the oxides exhibited relatively fast nucleation and growth agglomeration behaviour. It was also observed that the granules produced from the clay had higher tensile fracture strength and were more stable in acidic environment than that of oxide minerals.
