The semiconductor mechanism of dissolution and the pseudo-passivation of chalcopyrite
TL;DR: In this paper, the semiconductor mechanism of dissolution of chalcopyrite has been investigated and shown to be responsible for the slow dissolution of the material, in particular, the semiconducting properties.

Effects of pyrite and bornite on bioleaching of two different types of chalcopyrite in the presence of Leptospirillum ferriphilum
Hongbo Zhao,Jun Wang,Jun Wang,Xiaowen Gan,Xihua Zheng,Lang Tao,Minghao Hu,Yini Li,Wenqing Qin,Guanzhou Qiu +9 more
TL;DR: The effects of pyrite and bornite on bioleaching of two different chalcopyrite samples by Leptospirillum ferriphilum were studied for the first time and were potentially useful in interpreting the inconsistence of the researches of chalCopyrite hydrometallurgy.

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.
