Summary: This study proposes a new approach of co-utilizing COPR and C-bearing dust during limonitic laterite sintering process. The results indicate that, while 6% COPR and 8% C-bearing dust were added, the tumble index and yield of the sinters were basically equal to those of the blank samples. The obtained sinters were identified as nontoxic, and no secondary waste was generated throughout the clean utilization process.

Summary: The environmental risks of Cr in different types of soil are significantly different, mainly determined by the valence and occurrence form of Cr controlled by the soil constituents and properties. Additionally, the stable form of Cr in the black soil column after the reaction suggests that soil organic matter can be utilized as a potential environmentally friendly remediation material for Cr(VI) contaminated soils at COPR sites.

Summary: In this study, an eco-friendly and practical technology was developed to effectively stabilize and recover Cr(VI) in Chromite Ore Processing Residue (COPR) via a combination of FeSO4 reducing agent and hydrothermal treatment. The stable spinel phase product formed during detoxification facilitated the magnetic separation of ferrochrome resources. Under optimal hydrothermal conditions, the total Cr leaching concentration of treated COPR was significantly reduced, well below regulatory limits, making it a suitable raw material for the steel industry after magnetic separation. This work provides important insights for the harmless disposal and resource utilization of other chromium-containing hazardous wastes.

Summary: Microwave irradiation was used to enhance the de-contamination of chromite ore processing residue (COPR) dominated by zero-valent iron (ZVI). Factors such as liquid to solid ratios, ZVI to COPR mass ratios, and acid dosage significantly influenced the reduction of COPR in the MW system. The coupled process was found to be more effective in incorporating treated COPR into geopolymer-based crystalline microstructures compared to subsequent ZVI reduction and MW irradiation.

Summary: In this study, co-pyrolysis of sewage sludge (SS) and Ca (H2PO4)(2) was conducted to produce biochar with stable heavy metals. Optimal co-pyrolysis conditions were determined as a blended ratio of 15% Ca(H2PO4)(2), a final temperature of 650 degrees C, a heating rate of 15 degrees C min(-1), and a retention time of 60 min. The potential stabilization mechanisms of heavy metals included increased biochar surface porosity, formation of metal phosphates, and reactions among inorganic substances, pyrolysis products, and heavy metals. The environmental risks posed by heavy metals were significantly reduced from 65.73 in SS to 4.39 in the biochar derived from co-pyrolysis with Ca(H2PO4)(2).

Summary: The catalytic ozonation of porous carbonaceous materials holds great potential for the treatment of refractory organic contaminants. However, the formation mechanism of hydroxyl radicals and the contribution of reactive oxygen species (ROS) remains contentious. This study used highly porous biochar (HPB700) as a model material and investigated the formation, evolution, and contribution of ROS during catalytic ozonation. The results showed that free hydroxyl radicals were generated during the process, and hydrogen peroxide played a key role in their formation. The findings enhance our understanding of hydroxyl radical formation and the role of different ROS in pollutant degradation.
