Static heap leaching tests
WebOct 1, 2014 · Permeability testing was performed at effective stresses ranging from 34.5 to 3,166 kPa (2 to 170 m of ore), to span the range of operational stages of a typical copper heap leach facility. The results of these permeability tests showed that at low effective stress, the GCL permeability was greater than 10 -6 cm/sec. http://geoserver.ing.puc.cl/info/conferences/PanAm2011/panam2011/pdfs/GEO11Paper753.pdf
