Batalhão Authors are invited to submit contributions on, but not limited to, the following topics: • Production of critical raw materials by urban mining. • Greener technologies for critical minerals obtaining. • Hydro, pyro and biohydrometallurgy to obtain metals from low-grade ores and residues. • Recovery of metals from tailings, residues, slags and wastes of mineral processing. • Exploration of low-grade mineral resources. This Special Issue aims to gather high-quality research that explores the latest advancements in sustainable mining for critical minerals production, with an emphasis on promoting sustainable development and a circular economy within the context of a green energy transition. Novel extraction methods, but not restricted to, are: • Use of organic acids for extraction of metals – leaching and separation steps using organic acids as citric, DL-malic and oxalic from electronic wastes and mining sources (primary and secondary) to obtain metals as Li, Co, Nb, Ta, Mn, Ag, Au, and Cu. • Development of new polymeric membranes for separation and purification of critical raw materials – design of membrane materials for separation of metals and organic compounds by nanofiltration, ultrafiltration and electrodialysis. Application of commercial membranes is also considered. • Separation, purification, and capture of CO2 from industrial processes, including recycling, are also considered – design of new materials, application studies and scale-ups.

We are happy to share our latest publication in the Journal of Environmental Chemical Engineering (Elsevier). This work investigates the performance of #polymeric and #inorganic #sorbents to recover #traceelements (#cobalt, #gallium, #germanium, #rubidium, #strontium, #caesium) from #saltworks #bittern. The study evaluates polymeric sorbents with aminophosphonic functional groups (IRC747 and S940), impregnated organo-phosphinic groups (MTX8010), and inorganic sorbents (SbTreat—sodium titanium oxide hydrate, SrTreat—zirconium oxide, and CuHCF—copper (II) hexacyanoferrate).

Biocarst develops similar process using microorganisms to sequester CO2 on mine tailings

Beside the GlyCat technology that reduce cyanide consumption by 80%, Dundee have just developed a new hydrometallurgical cyanide-free process that cuts gold leaching time by 90%. The new process uses sodium hypochlorite with a catalytic amount of sodium hypobromite in acidic conditions to put the gold into solution. Contact time is short, done at ambient temperature and pressure and all chemicals are recycled within the circuit. This process is environmentally friendly, efficient and cost-effective alternative to cyanide. 

Currently, lithium extraction is exclusively from hard-rock ores and continental brines, with continental brine resources being more abundant than hard-rock ores. The technology currently used to extract lithium from continental brine deposits relies on open air evaporation to concentrate the brine. Large volumes of water, 100–800 m3 per tonne of lithium carbonate, depending on the deposit, are lost through evaporation, raising concerns about the overall sustainability of the process. Furthermore, continental brine concentration is intrinsically slow, taking 10–24 months, which means that this process is not responsive to short-term changes in demand. Sodium is abundant and doesn't face these issues. 👉 Read more about lithium extraction here: https://www.rfr.bz/llnbsd4

> Cyanide leaching has been the dominant method for extracting gold and other precious metals for decades. However, its significant drawbacks have driven the scientific community to seek alternatives. Cyanide is highly toxic, posing a severe threat to human health and the environment in case of spills or improper disposal. Stringent regulations and public pressure have further emphasized the need for a safer and more eco-friendly approach. While alternatives like thiourea have been explored, they often fall short in terms of efficiency or environmental impact. This ongoing challenge spurred research into glycine leaching, a novel technique with the potential to revolutionize the mining industry.   > Pioneered and patented by researchers at Curtin University in Australia, glycine leaching offers a game-changing solution. Glycine, a simple amino acid commonly found in food, exhibits remarkable properties for metal extraction. Unlike cyanide, it is non-toxic, readily biodegradable, and poses minimal environmental risks.   > One of the key advantages of glycine leaching is its selectivity. Glycine can effectively target and leach desired metals like gold, silver, and copper, while leaving behind unwanted materials like iron and arsenic. This selectivity reduces the need for additional processing steps and minimizes the generation of hazardous waste. Furthermore, glycine leaching demonstrates remarkable versatility. It can function independently with the aid of strong oxidants or synergistically when combined with other lixiviants such as cyanide, ammonia, and others. This adaptability allows for tailored processes depending on the specific ore composition and desired outcome.   > Another groundbreaking outcome is the patenting of the glycine leaching by researchers at Karadeniz Technical University. This patent paves the way for its application in various gold recovery scenarios, particularly in mercury-containing ores and artisanal mining tailings. Glycine leaching presents a safer and more sustainable alternative for the exploitation of these resources, where it can leach both gold and mercury simultaneously releasing mercury-free tailings to the environment. More importantly it aligns with the goals of the Minamata Convention on Mercury, aimed at eliminating mercury use and restricting of cyanidation process wherever mercury is found.   > In conclusion, glycine leaching technology offers a beacon of hope for the mining industry. As research and development progress, glycine leaching has the potential to revolutionize the way we extract precious metals, promoting a more sustainable and environmentally conscious future for the mining industry. #Responsiblemining #glycineleaching #goldmining #cyanide #greenmining #mercuryremoval #minamata #artisanalmining The illustrative picture sourced from https://lnkd.in/dJ45MAfN

It is projected that by 2027, the market for brine concentration technology (BCT) will grow to $21.1 billion. Mining, power generating, and desalination are among the businesses that are utilizing BCT, which is utilized to recover valuable minerals from wastewater. The industry is growing mostly because of increasing water scarcity and more stringent environmental laws. BCT is in higher demand due to technological advancements and growing use of zero-liquid discharge systems. 💎𝗕𝗿𝗶𝗻𝗲 𝗖𝗼𝗻𝗰𝗲𝗻𝘁𝗿𝗮𝘁𝗶𝗼𝗻 𝗧𝗲𝗰𝗵𝗻𝗼𝗹𝗼𝗴𝘆 𝗠𝗮𝗿𝗸𝗲𝘁 𝗗𝘆𝗻𝗮𝗺𝗶𝗰𝘀- 𝟭.𝗗𝗿𝗶𝘃𝗲𝗿: 𝗡𝗲𝗲𝗱 𝗳𝗼𝗿 𝘇𝗲𝗿𝗼 𝗹𝗶𝗾𝘂𝗶𝗱 𝗱𝗶𝘀𝗰𝗵𝗮𝗿𝗴𝗲 𝘀𝘆𝘀𝘁𝗲𝗺𝘀 𝗮𝗻𝗱 𝗴𝗿𝗼𝘄𝗶𝗻𝗴 𝘂𝘀𝗲 𝗼𝗳 𝗱𝗲𝘀𝗮𝗹𝗶𝗻𝗮𝘁𝗶𝗼𝗻 𝟮.𝗥𝗲𝘀𝘁𝗿𝗮𝗶𝗻𝘁: 𝗛𝗶𝗴𝗵 𝗰𝗼𝘀𝘁 𝗼𝗳 𝗯𝗿𝗶𝗻𝗲 𝗰𝗼𝗻𝗰𝗲𝗻𝘁𝗿𝗮𝘁𝗶𝗼𝗻 𝘁𝗲𝗰𝗵𝗻𝗼𝗹𝗼𝗴𝘆 𝟯.𝗢𝗽𝗽𝗼𝗿𝘁𝘂𝗻𝗶𝘁𝘆: 𝗖𝗵𝗲𝗺𝗶𝗰𝗮𝗹 𝗮𝗻𝗱 𝘀𝗮𝗹𝘁 𝗽𝗿𝗼𝗱𝘂𝗰𝘁𝗶𝗼𝗻, 𝗮𝗹𝗼𝗻𝗴 𝘄𝗶𝘁𝗵 𝗴𝗼𝘃𝗲𝗿𝗻𝗺𝗲𝗻𝘁 𝗶𝗻𝗶𝘁𝗶𝗮𝘁𝗶𝘃𝗲𝘀 𝗳𝗼𝗿 𝘀𝘂𝘀𝘁𝗮𝗶𝗻𝗮𝗯𝗹𝗲 𝗱𝗲𝘃𝗲𝗹𝗼𝗽𝗺𝗲𝗻𝘁 𝟰.𝗖𝗵𝗮𝗹𝗹𝗲𝗻𝗴𝗲: 𝗛𝗶𝗴𝗵 𝗽𝗼𝘄𝗲𝗿 𝗰𝗼𝗻𝘀𝘂𝗺𝗽𝘁𝗶𝗼𝗻 👉𝐂𝐥𝐢𝐜𝐤 𝐡𝐞𝐫𝐞 𝐭𝐨 𝐫𝐞𝐚𝐝 𝐢𝐧 𝐝𝐞𝐭𝐚𝐢𝐥-https://lnkd.in/dXWEV-YT 📌𝗞𝗲𝘆 𝗣𝗹𝗮𝘆𝗲𝗿𝘀 𝗶𝗻 𝘁𝗵𝗲 𝗕𝗿𝗶𝗻𝗲 𝗖𝗼𝗻𝗰𝗲𝗻𝘁𝗿𝗮𝘁𝗶𝗼𝗻 𝗧𝗲𝗰𝗵𝗻𝗼𝗹𝗼𝗴𝘆 (𝗕𝗖𝗧) 𝗠𝗮𝗿𝗸𝗲𝘁- ✔Veolia Water Technologies ✔Evoqua Water Technologies ✔H2O Innovation ✔Aquatech International ✔AquaChemie ✔IDE Technologies ✔Saltworks Technologies: Industrial Water + Lithium ✔SAMCO Technologies ✔Gradiant #BrineConcentration,#BCTMarket,#WaterTreatment,#BrineManagement,#WaterTechnology,#BrineSolutions,#TechInWater,#WaterRecycling,#BrineTech,#SustainableWater,#IndustrialWater,#WaterInnovation,#Desalination,#BrineTreatment,#WaterConservation
