MINING AND ORE PROCESSING FACILITIES WASTEWATER

Special treatment solutions for mining and ore processing wastewater - physicochemical processes and special chemical treatments

In mining and ore processing facilities; wastewater from ore washing, flotation, leaching, filtration and dewatering processes; contains high suspended solids, heavy metals, cyanide, sulfate and special chemical components. As PİLSAN CONSTRUCTION; we design, build and commission turnkey treatment plants that integrate physicochemical treatment, neutralization, precipitation and filtration processes according to the special requirements of this sector, providing discharge standards compliant with SKKY.

Ore Washing and Processing Wastewater
Wastewater from ore washing and processing processes; contains high concentrations of suspended solids, clay particles, heavy metals and process chemicals. Pre-treatment, precipitation and filtration stages are of critical importance.
  • High suspended solids removal (TSS > 5000 mg/L)
  • Clay and fine particle precipitation
  • Heavy metal removal (lead, zinc, copper, cadmium)
  • pH neutralization and chemical stabilization
  • SKKY compliant discharge quality (TSS < 30 mg/L)
Flotation and Leaching Wastewater
Wastewater from flotation and leaching processes; contains flotation reagents, cyanide, sulfate and special chemical components. Effective removal is achieved with physicochemical treatment and special chemical processes.
  • Cyanide removal and detoxification
  • Sulfate removal and precipitation
  • Neutralization of flotation reagents
  • Breaking down heavy metal complexes
  • High efficiency filtration systems
Dewatering and Waste Sludge Processing
Special systems for dewatering mining wastewater and sludge disposal. Processing and recovery of high solid content wastewater.
  • High capacity dewatering systems
  • Sludge thickening and filter press
  • Waste sludge stabilization
  • Water recovery and circular use
  • Sludge disposal and storage solutions
