    The leaching behavior of minerals from a pyrrhotite rich

    Due to decreasing ore grades and increasingly complex ore bodies, the heap leaching of sulfide ores is of increasing interest. In this research, the heap leaching phenomena of a pyrrhotite rich pentlandite ore was investigated for the first 150 days of operation in order to understand the phenomena taking place in the early phase of leaching in an industrial scale heap.
