Zambia’s mining sector requires specialized wastewater treatment solutions to meet environmental regulations and support sustainable operations.

Mining Wastewater Characteristics

• High suspended solids from ore processing
• Variable pH (often acidic from sulfide oxidation)
• Heavy metals: copper, zinc, cobalt, manganese
• Chemical reagents: cyanide, flotation chemicals
• High flows with significant variations

Treatment Objectives

• Remove suspended solids to meet discharge limits
• Neutralize acidity and adjust pH
• Remove heavy metals to acceptable levels
• Treat cyanide to non-toxic forms
• Enable water reuse in processing

Treatment Technologies

Physical Treatment

Screening, sedimentation, and clarification for solids removal.

Chemical Treatment

pH adjustment with lime/soda ash. Precipitation of metals with hydroxide or sulfide addition.

Cyanide Destruction

Natural degradation, INCO process, or Caro’s acid treatment.

Sludge Handling

Thickening, dewatering, and secure disposal of metal-rich sludge.

Regional Considerations

• Equipment availability and service support
• Chemical supply chain reliability
• Power supply consistency
• Local regulatory requirements (ZEMA)
