Economic feasibility has been studied for removal of copper from acid mine drainage wastewater by ion exchange. Ion exchange method has been used for removal of copper from industrial wastewaters. Experiments were conducted using packed bed column. The present study were carried out for solutions with concentrations of 100 mg/lit to 200 mg/lit and pH values of 3 to 6, using Indion 730, strong acid cation exchange resin. Under the present operating conditions considered, the strong acid type resin was found to bring down initial copper content by almost 46-56 % and at pH 5, 60% of copper removal for 200 mg/lit of initial concentration was found. The techno economic feasibility was then studied and the rate of return found to be 21% which is economically viable.

Abandoned Coal Mines

Abstract Acid mine drainage (AMD) of the abandoned coal mines of the Kizelovsky coal basin (the Urals, Russia) is one of the worst natural disasters in the region. Acidic sulphate waters with a high content of metals freely flow into the surface water bodies. Arsenic, found in elevated concentrations in AMD, is an element of concern due to its potential toxicity to humans and animals. The aim of this work is determination of chemical speciation of inorganic arsenic in AMD as well as the surface water and groundwater affected by mine drainage, and assessment the natural removal of As from mine drainage due to adsorption on precipitated hydrous ferric oxide (HFO). Geochemical speciation (PHREEQC) revealed that arsenic occurs in all water samples as As(V). Surface complexation model shows that, HFO induced by the natural attenuation process may remove 46–85% of total arsenic in AMD and only 28% in polluted groundwater (on average).
