Summary: This study proposes a alternative approach for the production of sulfuric acid using sulfur-oxidizing microorganisms, which shows potential application even in remote areas. The results indicate that Acidithiobacillus thiooxidans has higher sulfuric acid production compared to other consortia, making it suitable for bioleaching of rare earth elements (REEs) from phosphogypsum. The two-step bioleaching condition resulted in higher REEs extraction compared to one-step bioleaching.

Summary: This study investigated the bioleaching of vanadium-bearing smelting ash using Acidithiobacillus ferrooxidans. The results showed that Acidithiobacillus ferrooxidans had a high leaching potential for vanadium and could transfer reducible, oxidizable, and acid-soluble fractions into the leaching liquor. Therefore, bioleaching was proposed as an efficient alternative to chemical/physical processes for enhancing vanadium recovery from vanadium-bearing smelting ash.

Summary: Recycling valuable metals from spent lithium-ion batteries using an ultrasonic-assisted bioleaching process was studied. The results showed that metal extraction and bioleaching time were enhanced by ultrasonication, with 19% Co, 50% Mn, 34% Ni, and 67% Li extracted after 12 hours. The study also found that ultrasound with a power of 203.5 W for 10 minutes daily promoted the growth of Acidithiobacillus ferrooxidans.

Summary: The adsorption of jarosite and passivation of mineral surfaces negatively affect metal extraction and the fate of other elements in biohydrometallurgical processes. This study found that At. thiooxidans can catalyze the reductive dissolution of jarosite, with Na2SO3 being the most suitable electron donor for DIRSO.

Summary: Metallurgical dusts, by-products from steel manufacturing, can be a valuable iron feedstock alternative with high iron content. However, they also contain heavy metals, such as zinc, which hinder their full recirculation in the steelmaking process. This study investigates the use of bacteria to leach zinc from cast house dust while maintaining high iron concentrations. Experiments show that a co-culture of A. thiooxidans and A. ferrooxidans can effectively achieve zinc leaching with high iron enrichment.

Summary: This study discusses the enhancement of bioleaching outcomes on a laboratory scale by establishing optimal operational parameters based on a literature review. The use of a mixed inoculum of Acidithiobacillus thiooxidans and Acidithiobacillus ferrooxidans, supplemented with FeSO4 and S-0, and an initial system pH near 6.0, may lead to greater bioleaching efficiency. However, operational parameters should be established according to the type of sludge being treated, and the duration of bioleaching should be considered to avoid reducing dewaterability performance.

Summary: With the decrease in high-grade ore reserves, it is crucial to develop suitable metal extraction methods for processing low-grade materials. Bioleaching, an energy- and environmentally friendly process, is effective for processing copper and other sulfidic ores. Overexpression of licanantase protein in Acidithiobacillus ferrooxidans improves cell attachment and biofilm formation, enhancing the bioleaching efficiency of certain low-grade copper ores.

Summary: Bioleaching is an effective technology for remediating heavy metals pollution in sediments, but the pressure from bioleached metals may cause the spread of antibiotic resistance genes (ARGs). This study compared the changes in abundance of ARGs in bioleaching treatments using indigenous bacteria or functional bacteria agent, revealing that the addition of a functional bacteria agent resulted in a higher Cu removal ratio but also increased the relative abundance of ARGs. Future research should focus on developing a green technology that reduces both the absolute and relative abundance of ARGs during bioleaching.

Summary: The dissolution of diopside-bearing slag and its amorphous counterpart was studied to assess their recovery potential. It was found that K and Na were the most mobile elements leaching from glassy and diopside slag (up to 99%). Targeted metals like Cu and Zn were released in varying quantities from the two types of slag. The study also indicated that glassy slag is more susceptible to dissolution compared to diopside slag.

Summary: This study investigates the efficiency of bioleaching to extract metals from waste, showing over 90% efficiency for iron, aluminium, manganese, calcium, magnesium, and chromium. Cadmium, lead, and nickel were also solubilized at rates of 70%-80%. The effectiveness of bioleaching was not dependent on temperature, but process time and sample acidification were important factors.

Summary: This paper introduces a novel waste heat recovery method using the hot flue gas from a ship's engine to produce liquefied hydrogen while meeting the ship's air-conditioning requirement. A comprehensive feasibility assessment is conducted and an artificial neural network with a multiobjective grey wolf optimization method is used for optimization. The findings indicate the highest mean sensitivity index of the flash temperature and the best optimization scenario for exergy efficiency, CO2 emission reduction, and liquefied hydrogen cost.

Summary: In this study, PVDF-based anion-exchange membranes were designed to selectively separate nitrate from chloride. Experimental data showed that increasing the concentration of PVDF enhanced nitrate transport but also increased the membrane electrical resistance. The selectivity of nitrate was found to be independent of the membrane thickness and mainly driven by the increased affinity between the anion and the membrane.

Summary: This study focuses on the modification of a commercially available polyamide thin-film composite membrane with a zwitterionic material to enhance its fouling resistance. The modified membrane shows improved salt rejection and reduced permeability compared to the pristine membrane. Fouling tests demonstrate that the modified membrane has a lower fouling ratio and higher recovery ratio. The enhanced antifouling characteristics are attributed to the improved hydrophilicity resulting from the zwitterionic brushes and the salting-in effect.

Summary: A transmembrane electro-chemisorption system with authigenic acid and base was developed for enhancing ammonia recovery from strong ammonia wastewater. The system efficiently transformed ammonium into free ammonia, which was then adsorbed and recovered through transmembrane chemisorption. This system yielded pure (NH4)2SO4 product and produced valuable byproducts of pure hydrogen and oxygen. Higher applied voltage resulted in better ammonia recovery.

Summary: This study investigates the concept of using heat to enhance reverse osmosis (RO) desalination. The effect of temperature on water permeate flux, specific energy, permeate quality, and applied operating pressures is evaluated using an analytical model. The results suggest that under specific conditions, the tradeoff between savings in mechanical pump work and thermal energy input in thermally-enhanced RO can be favorable, leading to overall energy savings.

Summary: To meet the huge demand for lithium resources, there is an urgent need to develop a new efficient technology for lithium recovery from salt-lake brines. In this study, a selective membrane capacitive deionization system is reported, which achieves high lithium recovery capacity and rate through the use of materials with efficient intercalated pseudo-capacitance and a high specific area porous carbon. The use of a modified thin-coated membrane allows for selective Li+ recovery, and adjusting the concentrations of Li+ and Mg2+ in the feed solution enables higher Li+/Mg2+ selectivity.

Summary: In this study, a novel polydopamine-functionalized lignin-containing pulp foam evaporator with high-efficiency desalination and multi-contaminant adsorption capabilities was designed. The foam evaporator showed excellent light absorption, water absorption, thermal conductivity, and chelation abilities, allowing for solar evaporation and contaminant adsorption synergistically. It also exhibited potential applications in metal ion concentration and contaminated seawater treatments, and demonstrated superior biodegradability compared to poly-styrene foam. This foam material holds promise for developing multifunctional photo-thermal systems for solar-driven water purification.
