A process is provided for heap leaching ore to recover nickel The process is particularly effective for ores that have a tangible clay component (i e greater than about 10% by weight) The process includes sizing the ore (where necessary) forming pellets by contacting ore with a lixiviant and agglomerating The pellets are formed into a heap and leached with sulfuric acid to extract the
In heap-leaching the ore is placed on open-air pads and the cyanide sprayed over it taking several weeks to leach down to an impervious base The solution then pours off the pad into a pond and is pumped from there to a recovery plant where the gold is recovered
