Dec 01 2020 1 Introduction Heap leaching is a low cost flexible hydrometallurgical process for recovering valuable metals from low grade ores (Nosrati et al 2012) In this process the ore bed must be porous and permeable to permit flow of the leach solution (Lewandowski and Kawatra 2009a) However fine particles usually migrate into the porous structures and clog the natural flow.
Quoted operating costs (2002) based on current technology for leaching dumps and in place ore are between US$0 18 and US$0 22 per pound of cathode copper which are competitive with the unit costs of smelting refining Heap leaching has the additional cost of mining and transporting to the leach pad.
