APPLICATION OF THE FLOTATION TAILINGS AS AN ALTERNATIVE MATERIAL FOR AN ACID MINE DRAINAGE REMEDIATION: A CASE STUDY OF THE EXTREMELY ACIDIC LAKE ROBULE (SERBIA)
Petronijevic, N., S. Stankovic, D. Radovanovic, M. Sokic, B. Markovic, S.R. Stopic, et al.
Metals 10(1):16(2020)
Flotation tailings rich in carbonate minerals were created from a tailings deposit at the Majdanpek copper mine and applied to neutralize water from Lake Robule. Tests showed that after neutralization of the lake water to pH 7, over 99% of Al, Fe, and Cu precipitated, as well as 92% of Zn and 98% of Pb. Water was further treated with NaOH to remove residual Mn and Ag. After treatment with NaOH, all concentrations of metals in the lake water samples were below Serbian discharge limits for municipal wastewater. Results suggest that mining waste could be used for active neutralization of the acid mine drainage. The use of the mining waste instead of lime could reduce the costs of the active treatment of the acid mine drainage. This article is Open Access at https://www.mdpi.com/2075-4701/10/1/16
