DEVELOPMENT AND JUSTIFICATION OF EFFICIENT METHODS FOR RECYCLING WATER CONDITIONING AT PROCESSING PLANTS



Closed circulation of recycling water involves household and process effluents. The concentration of copper ions and commercial fat acids worsening flotation efficiency can be reduced by their sedimentation after preliminary mixing of effluent flows to adjust pH. Based on the data of thermodynamic calculations, the optimal modes of water treatment are proposed, and their efficiency is proved in the full-scale tests. The achieved results ensure reduction in concentrations of copper ions and commercial fat acids in effluents, expand recycling water supply and, accordingly, enable saving fresh water. The technical and economic indices of copper–molybdenum ore processing are not reduced in the conditions of closed water circulation.
