Bauxite mining, a key aluminum production process, can cause environmental degradation, soil erosion, and biodiversity loss. Reclamation measures like reforestation water management restore balance. Red mud, by-product of alumina production, enhance fertility plant growth in post-bauxite mining reclamation areas. Its alkalinity mineral composition reduce reliance on synthetic fertilizers, promoting sustainable addressing challenges. This study aimed to examine the impact red mud characteristics plants areas during bauxite land reclamation. was conducted post-reclamation area West Kalimantan. The experiment involved two treatments: application species revegetation plant. Plant consist Embeng, Forest Guana, Johar, Rambutan. used randomized block design with 24 experimental units. parameters measured included pH, organic carbon, nitrogen, phosphorus, exchangeable cations, cation exchange capacity, base saturation, while high percentage percentages increased stem diameter. findings showed that adding planting hole pH improved nutrient availability, enhanced post-mining at PT Antam, UBPB Embeng is highly regarded as suitable for re-vegetating after mining.

With the expansion of mining industry, environmental pollution from microelements (MP) and red mud (RM) has become a pressing issue. While bioremediation offers cost-effective sustainable solution, plant growth in these polluted environments remains difficult. Arundo donax is one few plants capable surviving RM-affected soils. To identify endophytic fungi that support A. different contaminated to inform future research combining mycorrhizal techniques with hyperaccumulator plants, we conducted field experiment. The study compared fungal communities grown uncontaminated, MP soils cadmium (Cd), arsenic (As), lead (Pb), RM-contaminated Our findings showed soil nutrient profiles differed by contamination type, Cd concentrations exceeding national standards (GB 15168-2018) RM characterized high aluminum (Al), iron (Fe), alkalinity. There were significant differences community structures across three types ( p < 0.001). Co-occurrence network analysis revealed exhibited competitive niche dynamics, whereas tended share niches. Notably, Pleosporales sp., which accounted for 18% relative abundance soils, was identified as dominant beneficial endophyte, making it promising candidate efforts. This provides valuable insights into role phytoremediation highlights their potential resources improving plant-microbe interactions environments.

Because of the strong alkalinity red mud, it is difficult to recycle, and long-term accumulation mud causes environmental pollution. The study shows that solidification characteristics bayer (RM) under action Ca(OH)2 (CH) are obvious. mechanical properties Bayer RM paste with different amounts CH at ages were tested. strength RMCH gradually increases increase in content age, reaching a turning point 26.4% CH, highest 28 days, 2.73 MPa. products characterized by XRD, FTIR, TG-DTG, SEM-EDS. results show main C-(A)-S-H, hemicarboaluminate, monocarboaluminate. In process, hydroxysodalite faujasite-Na react generate C-S-H, Al(OH)4−, Na+, then monocarboaluminate among which hemicarboaluminate transformed into presence calcite, further decomposes calcite. It provides basis for interaction mechanism between single substance research sustainable utilization mud.
