Abstract

Buchim Mine has been built 35 years ago on the well-known porphyry copper deposit Buchim. During these three and half decades of continuous production around the Buchim Mine were created surface waste dump where have been stored more than 130 Mt of waste and hydrotailing dam with more than 110 Mt of tailing. These secondary landfills for years have been considered as basic sources of anthropogenic influences and contamination of air, soils and especially waters. In this paper we would like to present ours latest findings in regards to copper contamination around the Buchim copper mine drainage system and adjacent copper leaching facility. Namelly, several so-called polluting hot-spots around the Buchim copper mine have been determined, which manifested pronounced acidic character of mine waters (pH 3.6-5.5) and increased copper concentrations of up to 800 mg/l Cu. After the leaching facility and closed water system were built, the influence of pollutants to surface and ground waters significantly decreased. Positive effects in regards to environmental pollution following their construction were indicated by the results of the 2012 monitoring and especially by the results of the 2013, 2014 and 2015 monitoring. According to the monitoring in 2013, copper values ranged from <0.01 to 1.6 mg·l-1 Cu while 2014 monitoring have shown even better results from 0.01 to 0.98 mg·l-1 Cu and pH 4.50÷8.40 and during 2015 from 0.1 to 0.38 mg·l-1 Cu for piezometers and from 0.01 to 0.05 mg·l-1 Cu for ground and surface waters, which itself speaks about the positive effects achieved with constructions of the copper leaching facility and engulfed drainage waters.
