Impact of the flotation tailing dumps on the living environment of Bor and protective measures

Abstract

In the southeastern Serbia, in the area of the municipality Bor, there are three flotation tailing dumps: FTD Bor, FTD RTH (the ore body H) and FTD Veliki Krivelj. The Flotation Tailing Dump Bor is abandoned, partly reclamated. The other two are active flotation tailing dumps. All three flotation tailing dumps are serious polluters of air, water and soil. The affected zones by dust from these tailing dumps threat large areas in a direction of dominant wind from the northwest direction. The affected areas by the impact zone of dust from: the Bor Flotation Tailing Dump amount to 18,361,074 m 2 , flotation tailing dump of the ore body H, 3,713,408 m 2 and Flotation Tailings Dump Veliki Krivelj, 16,077,805 m 2. The most effective measure against dust rising from dry areas by the wind is the use of reclamation with the phases of technical, agrotechnical and biological reclamation.

Applicability of the risk ranking methodology designed for water reservoirs to tailings storage facilities

“…As the subject of assessment, one of the most hazardous TSFs in Serbia is singled out, the TSF Veliki Krivelj in Bor. The risks associated with operating this facility have been discussed and studied on several occasions, providing an informed basis for a comparative analysis (Lekovski, Mikic, and Krzanovic, 2013;Zivković et al, 2014;NiŠić, Kneževic', and Lilic, 2018;NiŠić and Kneževic', 2018).…”

10.5937/mmeb1402081r = Remediation the tailing dump RTH in terms of stability

“…Ukoliko vode taložnog jezera dodiruju unutrašnju kosinu obodnog nasipa na zapadnoj strani jalovišta, stabilnost jalovišta je dovedena u pitanja, a naročito za vreme zemljotresa iznad 8 stepeni Merkalijeve skale. [10] Prodor flotacijskog mulja kroz obodni nasip izazvao bi ugrožavanje industrijskog puta i industrijske pruge i došlo bi do izlivanja mulja u Borsku reku, a poplavni talas bi ugrozio selo Slatinu i zemljište i vode u priobalju Borske reke do Timoka, a zatim i ušće Timoka u Dunav.…”

“…[10] Penetration of flotation sludge through the perimeter dike would cause a threat to the industrial road and railway and there would be a spillage of sludge in the Bor River, and a flood wave would endanger the village of Slatina and land and water in the coastal region of the Bor River to Timok, and then the mouth of Timok in Danube. [10] CURRRENT STATE OF DAM Stability calculation was done using the licensed program GeoStudio 2007, its part Slope/W, that is specialized in cases of limit equilibrium [1][2][3][5][6][7][8][9]. The calculation was done by the method of Morgenstern -Price.…”

Stability of Solid Residue After Integral Treatment of Acid Mine Drainage

“…During the exploitation and flotation processes, approximately 99% of the ore is converted into flotation tailings (Brierley & Brierley 2013, Dold 2008. Flotation tailings are natural or artificial lagoons for disposing of liquid flotation tailings deposits (crushed comminuted material and chemically contaminated water) (Lekovski, Mikić & Kržanović 2013). Namely, flotation tailings were identified as one of the primary sources of heavy metals in the environment (Qin et al 2017).…”
