Investigating the efficiency of using nepheline-based aluminosilicate coagulant

Summary

The results of investigating the efficiency of using aluminosilicate coagulant produced with the help of advanced technology of decomposing nepheline concentrate with 20–30% sulfuric acid are presented. The high efficiency of the produced chemical used for precipitating drill clay slicks, flotator discharge slurries and recycling water from apatite production; for removing copper, nickel, cobalt, fluorine, phosphorus and dissolved oil products from water is shown. The coagulant can be used for industrial and municipal wastewater treatment.
