TL;DR: In this article, a high-energy planetary mill was used to perform mechanical activation of chalcopyrite in dry-, moist-, and wet-milling modes, and their effects on Cu dissolution were distinguished.
Unesp-universidade estadual paulista campus de araraquara programa de pós-graduação em biotecnologia consórcios microbianos associados a ambientes de minas: obtenção, avaliação fisiológica e molecular
TL;DR: In this article, the authors developed different iron and sulfur oxidizer consortium to promote chalcopyrite (CuFeS2) solubilization, which was obtained from previous enrichment in a specific culture of 15 ore samples provided by Companhia Vale S.A.
Kinetics of the oxidation of copper(I) by oxygenin acidic chloride solutions
TL;DR: In this article, the kinetics of the reaction between copper and oxygen in aqueous chloride was studied by an amperornetric technique, and the rate of oxidation by oxygen was found to exhibit a complex dependence on the concentration of copper(l) and also to be inhibited by copper(ll) ions.

Formation, remobilisation and alteration processes at inactive hydrothermal vents: insights from elemental analysis of Cu-(Fe-)S sulfides from TAG, Mid-Atlantic Ridge
TL;DR: In this article , the authors analyzed chalcopyrite from five inactive seafloor massive sulfide (SMS) sites from the TAG hydrothermal field on the Mid Atlantic Ridge by electron probe microanalysis (EPMA) and laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) for 24 elements.

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.
