Impact assessment of mine drainage water and municipal wastewater on the surface water in the vicinity of Bor

Abstract

Izvod Rudarstvo i proizvodnja bakra u Boru, tokom proteklih sto godina, imalo je ogroman uticaj na životnu okolinu. Otpadne vode koje se generišu u pogonima RTB Bor zagađuju Borsku i Kriveljsku reku koje predstavljaju otvoreni kolektor za otpadnu vodu. Posle uliva Borske reke u Kriveljsku reku nastaje Bela reka koja se dalje uliva u reku Timok, odnosno reku Dunav. Za period istraživanja od 17. oktobra 2012. god. do 17. januara 2013. sprovedena je analiza rudničkih, drenažnih i komunalnih otpadnih voda. Za potrebe istraživanja i procenu negativnog uticaja otpadnih voda na površinske vode na terenu je sprovedeno merenje protoka, temperature, pH vrednosti, oksido/redukcionog potencijala i koncentracije rastvornog kiseonika u uzorcima vode. Takođe, određen je i sadržaja Cu, Fe 2+ , ukupnog Fe (T-Fe), As, Mn, Si, Ni i Al.

The study of leachability and toxicity of sludge after neutralization of Saraka and Robule AMD wastewaters

“…Sludge produced in the neutralization process of Robule AMD R4 (40) and stabilized on 105 o C shows higher leachability of zinc and copper than limit values. Sludge produced in the neutralization process of Robule AMD and stabilized on 200 o C shows higher leachability only for copper.…”

“…The copper mine Bor, within the operation scope of Mining & Smelting Basin (RTB) Bor, started mining operations in the year 1903. For more than one hundred years of mining, about 673.5 million tons of overburden and flotation tailings were deposited in and near the municiplity of Bor [37][38][39][40]. Also, over 29,000 hectares of land it has been by quality strongly degraded.…”

“…Also, over 29,000 hectares of land it has been by quality strongly degraded. The area of such agricultural degraded land from the total percentage of agricultural land of the Bor District amounts over 60 % [40].…”

“…During the decades of exploitation of ore from the open pit Bor at different locations ("Visoki Planir" -also called "Oštreljski planir", "Severni planir" dump of ore body "H" (RTH)) mine overburden and tailings were delayed [40].…”

“…The Robule lake (figure 1) located close to the Bor city is characterized by low pH value and high concentration of metals [40]. It was built during 1970s as a consequence of the depositing of the large amount of overburden, about 150 million tons, that formed Veliki Planir.…”
