Formation of Copper Carbonate Copper carbonate can form through several processes: Weathering of Copper Ores: Copper carbonate minerals often form as a result of the weathering of primary copper sulfide ores, such as chalcopyrite (CuFeS2). As these ores are exposed to weathering processes, copper ions are released and can react with carbonate ions in the environment. Reaction with Carbon Dioxide: When copper salts are exposed to carbon dioxide in the presence of water, they can react to form copper carbonate. For example: Cu2++CO32−→CuCO3Cu2++CO32−→CuCO3 This reaction can occur in natural settings or in laboratory conditions. Biological Processes: Certain microorganisms can facilitate the precipitation of copper carbonate through biological processes. These organisms can alter the local chemistry, leading to the formation of copper carbonate minerals. Synthetic Production: Copper carbonate can also be synthesized in controlled laboratory conditions by reacting copper(II) salts with sodium bicarbonate or sodium carbonate. This method allows for the production of pure copper carbonate for industrial and research purposes. #mineral #metals #geology #rocks #earthsciences #education #explorationgeology #bhpo #riotinto #exploration

How do high-grade rare earth element (REE) accumulations develop in regolith? Our 📜 *New Open Access Paper* 📜 , published today in Mineralium Deposita, discusses just that! In it, we find that localised REE accumulations of 12.37% total rare earth oxide (TREO) at the Kapunda Cu Mine in South Australia formed in response to the evolution of highly-acidic (pH < 3) weathering fluids. Contrary to popular belief (which suggests that acidic weathering fluids should favour REE *mobilisation* in regolith), these fluids expedited the dissolution of primary phosphate minerals (likely apatite), which resulted in the massive liberation of phosphate into the weathering solution. This phosphate then combined with dissolved REEs to precipitate and accumulate highly insoluble secondary minerals like rhabdophane, monazite and florencite - even under acidic conditions! As a passion project of mine for over 5 years now (having started as my MSc thesis), I am beyond happy to finally see this work published as the first chapter of my PhD. A massive thanks goes to Fang Xia, Caroline Tiddy and Ignacio Gonzalez-Alvarez for their patience and supervision over this time, as well as to co-authors joel brugger, Siyu (Shirley) Hu, Louise Schoneveld, Mark Pearce and Andrew Putnis for all of their invaluable contributions.

⚒️ #GözümüzYükseklerdeDeğilDerinlerde ⚒️ Fuchsite mineral is known as octahedral mica mineral containing chromium. chemical formula (KAl2(Al2 Si3 O10)(OH)2) represents an ideal muscovite mineral. Fuchsite mineral is formed by the entry of Cr into the system as a result of the reaction after metasomatism, and this formation can be shown as an example of supergene mineralization. In geochemical studies on fuchsite, before the fuchsite mineralization along the fault zones occurs in the host rock, It is suggested that CO₂+Cr, carried by fluids that come into equilibrium with ultramafic-mafic rocks, is formed as a result of the chemical reaction with these mica minerals. Research has shown that fuchsite minerals are widely developed in shear zones.

Global constraints on exhumation rates during porphyry copper formation and supergene enrichment: applications to exploration as illustrated from the Central Andes Evenstar et al. (2024): ....This paper uses new global datasets and previous work to review the critical processes required for porphyry copper formation and supergene enrichment.  https://lnkd.in/eSSmyeff

* Research Alert * We're pleased to share a new research paper from our The University of Queensland node: 'Soluble mineral flotation paradox: Improved recovery with no sign of collector adsorption on minerals signifies colloidal attraction between bubble-bound collector colloids and mineral particles', as appearing in Minerals Engineering 👇 https://lnkd.in/gQ4_W8Db #COEMinerals researcher paper co-author Ngoc N. Nguyen provided some insights about the research, highlighting the new foundational base knowledge it covers: "Flotation separates minerals based on the difference in surface properties of minerals. As such, reagents (called collectors) are added to tailor the surface of the targeted mineral to augment the difference in surface properties and improve the separation efficiency. However, for the flotation of water-soluble minerals, we found that the added collectors caused no changes in the mineral surfaces but substantially enhanced the separation efficiency, which challenges the conventional understanding of collectors’ function. This paper presents a new foundational basis to address this paradox and provides hints to achieving a better flotation separation of soluble minerals." Congratulations to all authors: Kangkang Sun, Ngoc N. Nguyen and Anh Nguyen.

🚨 New Research Alert! 🚨 A billion-year shift in the formation of iron ore deposits A recent study from The University of Western Australia in collaboration with researchers from Curtin University, Rio Tinto and CSIRO Mineral Resources reveals that iron deposits in the Pilbara region are up to a billion years younger than previously thought. Professors Marco Fiorentini and Steffen Hagemann, co-authors of the study, used new techniques to date the iron minerals, discovering their formation coincided with the breakup and formation of supercontinents. The new ages proposed in the study for the formation of the largest ore deposits on Earth opens opportunities to establish genetic links between iron and other critical metals that are key to the global energy transition.

Indium in ore deposits and mine waste environments: Geochemistry, mineralogy, and opportunities for recovery Mejías et al. (2023)... Indium is considered a critical element worldwide due to its specific function in low-carbon technology and its vulnerability to supply disruption. Highlights: The first collation of indium concentration across 45 minerals (microanalysis) The richest indium sphalerite is likely to be found in polymetallic Sn systems Indium in water and solid waste: 55,000× and 10,000× higher than natural levels Indium at pH < 4 is dissolved and at pH > 4 controlled by adsorption/precipitation Bioleaching as an environment-friendly option for indium recovery from mine waste https://lnkd.in/gBm9NBpk
