Cold Weather Heap Leaching Operational Methods

"Cold weather heap leaching can be grouped into two basic regions: Arctic and near Arctic, with various operational techniques or combinations of operating techniques dictated by latitude and site topography.The basic cold weather regions are Arctic areas, those areas above the Arctic circle (60° North latitude) and near-Arctic areas, (between 50° and 60° North latitude).As techniques and operational philosophy have advanced, heap leaching operations have moved into progressively colder regions.ABSTRACT ONLY"
