WASTEWATER TREATMENT OF GOLD FACTORIES
Keywords:
vacuum filter, gold-bearing ores, harmful chemical components, tailings, evaporation, thiocyanates, the water-insoluble simple, ejector, regeneration, xanthates, seepage.Abstract
This article aims to neutralize wastewater, clean it from various additives, reuse it in technological processes and make it environmentally safe. In the process of processing gold-bearing ores, effluents are formed - gold-free solutions, pulped vacuum filter cake, tailings of the sorption process, etc. The liquid phase of wastewater contains such harmful chemical components as cyanide and thiocyanate ions, complex cyanide anions of iron, zinc, copper, nickel, arsenic, lead, mercury compounds, etc. In the wastewater of enterprises using flotation enrichment and cyanidation, there are, in addition, organic flotation reagents - xanthates, pine oil, etc.
