Selective leaching of nickel from prereduced limonitic ...
acceptable nickel recovery. Generally, under AL conditions, nickel is more difficult to leach from limonite than from smectite (clay) and saprolite ores [3]. To achieve high nickel extraction, often high acid consumption is required, as high as one ton of H 2 SO 4 per ton of laterite ore, which inevitably leads to high concentration of residual acid
