Seloxium helps mining, refining and industrial companies to achieve their ESG goals by (1) turning their wastewater into a highly profitable and sustainable source of valuable metal resources or by (2) improving the purity and hence the value of highly concentrated metal processing or mining streams. Mining valuable metals from wastewater using Selectal™,  not only combats freshwater contamination but also turns effluent treatment plants into 'resource factories'.
