 Tongren City, Guizhou:  Manganese Recovery,
Water Reuse

• Guizhou has rich deposits of many minerals including manganese (Mn) used for battery production, etc.
• Manganese mining and processing accounts for 40% of GDP of Tongren City, Guizhou
• From March to August, the rainy season, the volume of Mn wastewater often exceeds mining company wastewater treatment capacities – forcing most companies in the region to close during this 5 month period
• LINX 600 system selectively removes Mn from pre-treated wastewater – in field test observed 86.5% Mn reduction, vs 63.5% TDS reduction
• Mn precipitation, followed by LINX 600 system deionization for waste water reuse, and concentrating the remaining Mn for return to pre-treatment can enable companies to work year round
