Summary: Chromium slag and copper smelting waste slag were used as raw materials to produce black ceramic tiles, reducing environmental pollution and increasing their utilization value. The color characteristics, phases, and microstructure of the ceramic tiles were analyzed, and the effects of different process parameters were investigated. The results showed that the optimal conditions for coloring the ceramic tiles were an Fe/Cr ratio of 1.5, sintering temperature of 1200 degrees C, holding time of 30 min, and cooling in the furnace. The ceramic tiles met the relevant national standards for compressive strength and leaching concentration of Cr(VI).

Summary: In this study, a solidified body (PG-S) was prepared by mechanical compression of a mixture of phosphogypsum, copper smelting slag, CaO, NaOH, and water. The resulting geopolymer material had a dense internal structure with a compressive strength of up to 21.3 MPa after curing for 28 days. The immobilization efficiency of PO(4)(3-)and F(-)reached 99.81% and 94.10% respectively, and the leaching concentration of heavy metals met the required standard. The study demonstrates the potential of utilizing phosphogypsum and copper smelting slag for resource utilization and backfill material.

Summary: The accurate understanding of arsenic (As) species distribution and their leaching toxicity in copper smelting slag is crucial for its efficient and safe disposition. Various analytical techniques were employed to investigate the As species in the slag and evaluate their potential toxicity. The results revealed that As existed in various forms in the slag, including water-soluble As, Cu-As intermetallics, Cu-As sulfides, as well as As incorporated in fayalite and glassy silicates. Flotation of readily soluble As and Cu-As intermetallics was effective in reducing the leaching toxicity of slag tailings and meeting the regulatory thresholds for As set by USEPA and SEPA.

Summary: Coppermaking from sulfide concentrates typically involves smelting and converting steps. However, in the continuous direct-to-copper smelting process, these steps are combined to reduce energy consumption and costs. Despite its advantages, a disadvantage of this process is the dissolution of copper in the slag, leading to significant recovery costs.

Summary: A novel application utilizing mechanochemical pre-treating and alkali leaching was developed for selective leaching of arsenic from copper smelter flue dusts. Mechanical-activated powders showed improved arsenic leaching efficiency and reduced activation energy, while consuming less alkali and sulfides and requiring shorter leaching time compared to traditional methods. Mechanical force promoted arsenic leaching by changing physical properties of the powders and converting As5+ species into more mobile phases in alkali solution within sulfides.

Summary: The separation of copper and arsenic has always been a major issue in the copper slag flotation process, with the presence of arsenic-copper alloys increasing the difficulty of separation, requiring finer grinding. Arsenic is oxidized into arsenate compounds during the process, while the transformation of copper and arsenic speciation affects the selectivity of separation. The study also highlights the risks of heavy metals in FSF slag and its flotation concentrate, emphasizing the need for cautious handling and utilization.

Summary: The study on slag tailings revealed the presence of arsenic in the form of maghemite and fayalite, with uneven distribution of arsenic-bearing minerals. The evaluation assessed the health risks to children exposed to the tailings, finding no harm to their health, but identified a potential higher hazard index with longer activity time of workers in the tailing workshop. Despite the certain bioavailability of arsenic in the slag tailings, it was not found to adversely impact human health.

Summary: The current research on metallurgical remains from Bronze Age period in northeast Yunnan is insufficient. In order to study the smelting technology, samples of slag and mineral excavated from the Yubei Di site were examined and characterized. A simulation was conducted to generate a phase diagram that accurately depicts the melting procedure. The results showed that the slag mainly came from the reduction and smelting process of sulphur-containing copper oxide minerals into copper, indicating a lack of advanced techniques and the use of primitive methods.

Summary: This study investigated the long-term leachability of antimony (Sb) in a smelting residue immobilized by three commercial micro-sized zero-valent iron (ZVI) products. The results showed that all ZVI treatments efficiently immobilized the Sb in a short term (14 days), but the longer aging process (120 days) easily resulted in the reduction of Sb immobilization. The binding of Sb with amorphous phase Fe oxyhydroxides derived from ZVI corrosion played a dominant role in the Sb immobilization efficiency.

Summary: Research has shown that forest soils in the Czech Republic have isotopic signatures introduced by lead pollution, likely stemming from widespread atmospheric pollution, with floodplain forests showing different isotopic signatures potentially due to more materials from the river bed or surface runoff. These findings may assist in determining background values for soil lead and monitoring the state and health of forests in the Czech Republic for future conservation efforts.

Summary: This study investigates the behavior of Pb and its isotopes in forest soils affected by wildfires at different temperatures. The results show that high-temperature fires do not lead to significant accumulation of Pb, but result in a slight increase in Pb isotopic ratios. On the other hand, low-temperature fires result in Pb accumulation and a decrease in Pb isotopic ratios. Additionally, the study suggests that the temperature of a forest fire can potentially be determined from the Pb isotopic signatures of the burned materials.

Summary: Magnesium, calcium, and strontium isotopes were studied in a Central European headwater catchment recovering from acidification caused by acid rain. The sources of these base cations in runoff were constrained using a combination of isotope and non-isotope data. The isotopic composition of Mg, Ca, and Sr in precipitation, throughfall, and runoff were monitored, and various minerals were analyzed. The results suggest that biotite is the main source of geogenic Mg, while apatite and plagioclase are the likely sources of geogenic Ca. Plagioclase weathering contributes to a significant proportion of geogenic Sr in runoff.

Summary: Extensive mining and smelting have led to the decline in soil quality in Luanshya. The local smelter is the main source of contamination, with high concentrations of copper observed near the smelter. Lead contamination in the soils is not derived from the smelter but from historical usage of leaded gasoline. Copper leaching is a concern, and most of the copper is released from anthropogenic particles. The excess copper in the topsoils is bound in smelter-derived particles, which show signs of inefficient smelting process and susceptibility to weathering.

Summary: This study reveals that chronic exposure to PM induces chronic inflammation and development of COPD by dysregulating NAD+ metabolism and subsequent SIRT1 deficiency in pulmonary macrophages. Activation of SIRT1 by resveratrol effectively mitigates PM-induced inflammation and COPD development.

This study investigates the transfer and impacts of polystyrene microplastics in an estuarine food chain. The results show that microplastics can be transferred through the food chain, although the transfer rates are low. The exposed organisms exhibit stress responses, suggesting the potential risk of microplastics reaching humans through the food chain.
