Mining and copper production in Bor, in the past hundred years, had a huge
impact on the environment of town, but also in a wide region. In the area of
Bor, in the zone of Mining and Smelting Company (RTB) activity, over 29,000
ha of land under forests and fields is degraded. The area of degraded
agricultural land in the Bor municipality is over 60% of total agricultural
land. Wastewater, generated in the sites of RTB Bor, pollute the Bor River
and Krivelj River, which still flow into the Timok River and Danube River.
These pollutions are often presented by low pH value, increased content of
heavy metal ions, suspended particles and fine particles of flotation
tailings, which is deposited in the valleys of these rivers on the area of
over 2000 hectares. 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)) gangue and tailings
were delayed. The largest amount of tailings, about 150 million tons, was
postponed on location Visoki planir. The effect of the mining waste and the
impact of the whole process of processing copper ore to the final products on
the environment, was conducted during the 4th study period of the project
"Management of mining waste-tailing dump in the Bor region," supported by the
Japan Society for the Promotion Science (Eng. Japan Society for the Promotion
of Science) and the Japan international cooperation Agency and the Ministry
of environment, Mining and Spatial planning of the Republic of Serbia.
Influence of season on the level of pollutants in soil and water, the impact
on water quality in the river Timok and the River Danube, was conducted
during first three periods of project. This paper presents the results of the
third study period. The third period of research, which was conducted over a
period of 17. 10. 2012 to 17. 01.2013 year, included a review of pollution
sources and define their impact on the environment. The study included the
following sources of pollution: mining waste and drainage water originating
from the active mine (Bor pit , field 1 Krivelj large tailings, flotation
tailings in Bor RTH, metallurgical water), as well as the drainage water from
the flotation tailings, which are no longer in operation (field 2 flotation
tailings Great Krivelj, drainage water from the old Bor flotation tailings),
the old inactive landfill mine gangue (Saraka landfill, Veliki planir -
tailings from the old Bor mine, landfill mine gangue from mine RTH) and the
city - urban waste water, which are discharged without treatment directly
into the watercourse Bor River. Wastewater directly pollute Bor River and
