A review of the structure, and fundamental mechanisms and kinetics of the leaching of chalcopyrite.
TLDR
There is general agreement in the literature that chalcopyrite leaching is significantly affected by solution redox potential with an optimum E(h) range suggesting the participation of leach steps that involve both oxidation and reduction.About:

Impact of mechanochemical effect on chalcopyrite leaching
TL;DR: In this paper, two circuit layouts that may assist mechanochemical effect in order to enhance leaching were suggested. But the only operational variable is milling time that results different levels of specific energy.

Generalized Gradient Approximation Made Simple
TL;DR: A simple derivation of a simple GGA is presented, in which all parameters (other than those in LSD) are fundamental constants, and only general features of the detailed construction underlying the Perdew-Wang 1991 (PW91) GGA are invoked.
