Mining Wastewater and Tailings Treatment Solutions
Mining and mineral-processing water circuits contain fine particles, dissolved metals, flotation reagents, salts, oils, and variable suspended-solids loads. Effective treatment requires the chemical program, water balance, solids-separation equipment, and reuse target to be considered as one system. GN New Chem provides coordinated chemicals, equipment, process design, and field support for mine-water and tailings projects.
Typical Customer Challenges
- High and fluctuating suspended solids, turbidity, color, hardness, salinity, or dissolved metals.
- Slow settling of ultrafine particles and poor clarification in thickeners or ponds.
- Difficult tailings dewatering, low cake solids, and high freshwater consumption.
- Mismatch between reagent dosing, mixing, thickening, centrifugation, filtration, and water-reuse requirements.
GN Integrated Solution Approach
- Water and tailings analysis, settling tests, jar tests, and dewatering trials.
- Selection of coagulants, flocculants, heavy-metal removal chemicals, scale inhibitors, defoamers, decolorizing agents, and other process chemicals.
- Process design for clarification, thickening, flotation, metal precipitation, sludge conditioning, centrifugal or pressure dewatering, filtration, and water reuse.
- Integration with vibrating screens, hydrocyclones, decanter centrifuges, dewatering screens, slurry tanks, pumps, and modular treatment systems from the GN group.
- Site trials and continuous optimization according to throughput, overflow clarity, cake moisture, reagent consumption, and reuse quality.
Value to the Customer
- Clearer overflow water and improved recovery for process reuse.
- Higher tailings dewatering efficiency and lower stored or transported waste volume.
- More stable plant performance despite ore and water-quality variation.
- Reduced freshwater demand, environmental footprint, and total treatment cost.
Typical Applications
Mine drainage, mineral-processing wastewater, tailings thickening and dewatering, coal and aggregate washing water, metal-bearing wastewater, quarry slurry, and closed-loop process-water reuse.
