Bio-treatment and water reuse as feasible treatment approaches for improving wastewater management during flotation of copper ores
Shengo, LM & Mutiti, WNC
Abstract
Established and emerging technologies for
treatment of flotation wastewaters are compared and discussed
in the context of their applicability during the
management of wastewaters from Cu–Co ores processing
through flotation in the Katanga province of the Democratic
Republic of Congo. The effects from water recycling
on water quality and flotation performance are briefly
presented in parallel. The ore processing schemes and the
wastewater management practices at two operational concentrators
are illustrated as study cases and their peculiarities
outlined. A reference to a copper concentrator in a
nearby Zambia is addressed for comparative purpose.
Based on analysis of the findings, the clarification, biotreatment
inside the tailing ponds or the use of constructed
wetlands as polishing stage prior to water reuse are suggested
as feasible treatment approaches in view improving
the management practice of flotation wastewaters during
the dressing of copper ores in the Katanga province.
