The Neoproterozoic Throssell Range Group, Western Australia: A Peri‐Marginal Continental Basin in Rodinia and Its Implications for the Centralian Superbasin

Basin Research, Volume 38, Issue 1, January–February 2026.
This study of recent exploration drillcore reveals two sequences separated by a disconformity. Basal alluvial fan to shallow marine lithofacies suggest reactivation of basement faults, and a distinct upwelling signature points to a flooded margin, controlled by differential subsidence of diverse Proterozoic lithosphere.

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.

Evolution of Solid Products Formed During the Cathodic Decomposition of Chalcopyrite at Different Energetic Conditions in Acetic Acid

Metals
This paper presents a systematic analysis of the solid products formed during the cathodic decomposition of chalcopyrite using the acetic acid system. The reduction of chalcopyrite was assessed using different electrochemical and surface characterization

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.

Efficient and Green Flotation Separation of Molybdenite from Chalcopyrite Using 1-Thioglycerol as Depressant

Metals
The effective and environmental separation of chalcopyrite and molybdenite has long presented a challenge in mineral processing due to their similar floatability and close association at room temperature. This study explores the non-toxic 1-thioglycerol (

Electrochemical Behaviour of Chalcopyrite in Chloride Solutions

Metals, 2019
Due to the depletion of oxidized copper ores, it necessitates the need to focus on metallurgical studies regarding sulphide copper ores, such as chalcopyrite.

Novel pathway of chalcopyrite formation at low temperature in microenvironments of acidic, metal-rich sediments

Communications Earth & Environment
Chalcopyrite (CuFeS2) is the main source of copper worldwide and is usually formed at high temperature. Its occurrence at low temperature is poorly documented, and the mechanisms controlling its formation remain uncertain.

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

Studies on chalcopyrite (I)

The Journal of the Japanese Association of Mineralogists, Petrologists and Economic Geologists, 1962
Thermal transformation of chalcopyrite in argon atmosphere has been studied in temperature from 200°up to 1000°C, using the thermogravimetric, X-ray analyes and erflected microscopic examination. Both of the thermogravimetric and differential thermal analyses curves suggest some endouthermic eraction or transformation, as formerly recognized, at 540 ...
