Quantum-Chemical Method for Selection of a Collecting Agent to Recover Zinc and Copper(II) Cations in Flotation of Mine Waste Waters

摘要

The authors set forth the well-grounded selection of effective agents: terephthalic esters, distinguished for the optimal set of quantum-chemical parameters of the agent,reactivity to recover zinc and copper(II) from the process waste water, propose a new-developed complex collecting agent ROL and report the investigation into the mechanism for recovery of zinc and copper(II) by this agent. The resource-renewable process flow sheet:is proposed to treat mine-and-processing waste waters, rich in copper and zinc content to produce a concentrated product.
