Overview of geomembrane history in the mining industry1

2016-6-13  Mining uses geomembrane liners principally for three areas: evaporation (or solar) ponds for recovery of salts, heap leaching of mineral-bearing rock, and disposal of mill tailings (rock that has had most of the mineral value removed). Evaporation ponds and heap leaching are the largest applications of geomembranes in mining, and heap leaching is the most complex. Given the size and complexity, heap leaching will be the focus of this paper, but other areas will also be discussed. A good introduction to heap leaching is given by Thiel Smith (2004). A large Andean valley fill heap leach
