HEAP LEACH PAD DESIGN AND CONSTRUCTION PRACTICES IN

The most known leach pad liner failure in the mining industry is Summitville in Southern Colorado. Although no known heap stack failures occurred at Summitville, there was a possibility that the exposed pad liner may have been damaged by an avalanche debris slide during early stacking operations. Several less known leach pad heap slope failures occurred between 1985 and 1993 at mine sites in

Leaching Mining Fundamentals

Leaching is a chemical process in mining for extracting valuable minerals from ore. Leaching also takes place in nature, where the rocks are dissolved by water. Post leaching, the rocks are left with a smaller proportion of minerals than they originally contained. The leaching process in mining is carried out either as heap leaching or insitu leaching.
