A study of the impact of blast induced conditioning on leaching performance

Physical and chemical transformations of gangue materials during leaching of copper sulphides, and their influence on copper leaching kinetics

“…Leaching improvements have been obtained by utilizing crushing techniques such as the highpressure grinding roll (HPGR), which induces a high level of microfracturing that increases diffusion rates in the gangue (Ghorbani et al, 2013). The influence of microfracturing produced by blasting on copper leaching recoveries has been also investigated (Parra et al, 2015).…”
