1. Introduction. Three major destination groups, characterized by a cut-off grade criteria and ore type, represent the places in the mine where the material receives specific treatment after its delivery from the pit: leach dumps, waste dumps and mill (Hustrulid, Kuchta, & Martin, Citation 2013).Dump leaching facilities are built to receive and treat low-grade ore …Web
