The wet-process production of antimony trioxide is a key route in the antimony industry; however, the process involves acidic media, hazardous off-gases, and wastewater containing heavy metals, posing risks of environmental pollution and safety accidents if not properly managed. Therefore, establishing a systematic environmental protection and safety management system is crucial.

Environmental measures: Off-gases from the leaching stage are treated in absorption towers to recover acidic gases; wastewater undergoes treatments such as lime neutralization and sedimentation before being discharged in compliance with standards or recycled; solid waste is properly handled, allowing for the recovery of valuable metals or safe landfill disposal.

Safety measures: Comprehensive standard operating procedures are established, and employees receive safety training; safety warning signs are installed in production areas, and protective gear as well as emergency rescue equipment are provided; equipment undergoes regular safety inspections and maintenance to prevent incidents such as leaks, spills, or drips.

Through the coordinated implementation of these environmental and safety measures, the wet-process production of antimony trioxide can significantly reduce environmental risks and occupational hazards, achieving green, safe, and sustainable production.
