Chalcopyrite dissolution in cupric chloride solutions [PDF]
, 2009 Hydrometallurgical technology offers the possibility of processing low-grade or small copper ore bodies and concentrates economically. Chloride solutions have become of great interest, having high leaching kinetics and no passivation of sulfide minerals.

Journal of Geophysical Research: Planets, Volume 131, Issue 8, August 2026.Abstract Meteorites serve as an exceptional source of insight into our planet and the Solar System. Most meteorite fragments were recovered hundreds to thousands of years after their fall, and therefore exhibit varying degrees of terrestrial weathering, which has altered or completely removed weather‐sensitive mineral phases.

Effect of redox potential on chalcopyrite dissolution imposed by addition of ferrous ions
Eclética Química, 2018 Copper is a metal with a great economic interest and about 70% is found in nature in chalcopyrite form (CuFeS2). However the chalcopyrite dissolution is a challenge for industries as well as researchers because of its slow dissolution kinetics.

Leaching of a Mongolian chalcopyrite concentrate
Mongolian Journal of Chemistry, 2018 A Mongolian chalcopyrite flotation concentrate was leached using sodium hypochlorite adjusted to different pH using hydrochloric acid. It was found that using a starting pH of below 5.0 resulted in more efficient leaching.
