Abstract
The current technologies of mineral mining, processing and beneficiation require introduction of water circuiting. A common ecological and technological objective is in this case reduction of concentration of copper and commercial-grade fat acid ions that worsen flotation. A promising way of reaching the set objective is preliminary mixing of different waste water flows with maximum concentrations of the specified ions. The thermodynamic calculations justify optimized water treatment modes when engineering-and-economic performance of copper-molybdenum ore dressing remains unaltered, consumption of fresh natural water is lowered, and water supply is enhanced.
