Heap leaching of nickel containing ore - patentcut
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 ...
