Effect of Mechanical Activation on Electrochemical Properties of Chalcopyrite in Iron-Containing Sulfuric Acid Solutions

Metals
Mechanical activation significantly enhances the leaching of chalcopyrite, a process that is fundamentally electrochemical in nature. Thus, a comprehensive understanding of its impact on the electrochemical behavior of chalcopyrite in leaching systems is

On the Chalcopyrite inclusions in Sphalerite

Boletim da Faculdade de Filosofia, Ciências e Letras da Universidade de São Paulo. Mineralogia, 1952
Uma das finalidades do presente trabalho foi medir as porcentagens de inclusões de calcopirita em cristais de esfalerita, que formam concrescimento de ocorrência relativamente frequente nas jazidas hidrotermais. Parece existir uma relação entre porcentagens de inclusões e intensidade hidrotermal dos depósitos, como também entre porcentagens de ...
