Designing the SART process – A review - ScienceDirect

2018-3-1  For these cases, some alternatives of cyanide leaching have been proposed using the SART process to recover copper from cyanide solution. One alternative is to use cyanide leaching after acid leaching ( Dreisinger et al., 2008 ), and the second alternative is a cyanide leaching of the whole ore ( Estay et al., 2013c ).
