Despite closure regulations being recent in Brazil, many mining companies are attempting to adopt best practice and are facing the challenge of closing their mines properly instead of simply complying with current To address the potential hazard associated with the historic tailings disposal practices, REM- Revista Escola de Minas,, Dewatered stockpiling (dry stacking) is a safer alternative to tailings dams (Rico et al., 2008, [3]) for tailings disposal; however, this method has not yet been used in iron ore mines in Brazil, where geotechnical conditions and abundance of water are favorable for the use of tailings dams..
The tailings disposal facility at Bogoso/Prestea consists of four areas: TSF 1, which is inactive and is currently being decommissioned; TSF II cell 1 /2 for CIL tailings; TSF II cell 2A for CIL tailings and TSF III cell for flotation tailings. The total area is about 380 ha with 60 ha in active rehabilitation (Thorpe and Oboro-O‟fferie, 2009). tailings is normally far in excess of the liberated resource, and the tailings often contain potentially haz-ardous contaminants. A priority for a reasonable and responsible mining organization must be to proac-tively isolate the tailings so as to forestall them from entering groundwaters, rivers, lakes and the wind.
The collapse of a mine tailings dam and subsequent flood in SE Brazil on 5 November 2015 was preceded by a small‐magnitude seismic sequence. In this report, we explore the spatiotemporal associations between the seismic events and the accident and discuss their possible connection. Tailings are mixtures of crushed rock and processing fluids from mills, washeries or concentrators that remain after the extraction of economic metals, minerals, mineral fuels or coal from the mine resource (e.g., Fig. 1a; Hudson-Edwards et al., 2001, Younger and Wolkersdorfer, 2004, Lottermoser, 2007).

Brazil’is’a’country’withvast’continuous’andalmost’square The tailings disposal facility at Bogoso/Prestea consists of four areas: TSF 1, which is inactive and is currently being decommissioned; TSF II cell 1 /2 for CIL tailings; TSF II cell 2A for CIL tailings and TSF III cell for flotation tailings. The total area is about 380 ha with 60 ha in active rehabilitation (Thorpe and Oboro-O‟fferie, 2009).
Tailings Dam Construction Design of slime is likely to slide and cause the dam to break away. The procedure usually adopted in such cases is to separate the tailing into coarse sand and fines in a classifier, and to use the coarse product to build up the wall ; the remainder of the pulp is discharged into the interior of the dam. Examples of mining-related situations that are covered by CAA-based regulations include dust emissions that accompany operations or tailings disposal in impoundments, exhaust emissions from heavy equipment, and emissions from processing facilities, such as smelters.

MINING’S MANY FACES Environmental Mining Law And Policy in Canada The Canadian Institute for Environmental Law and Policy ACKNOWLEDGEMENTS The Institute would like to thank the International Development Research Centre for its assistance in the completion of this report. 1.1 What regulates mining law? Mining in Brazil is regulated in the Federal Constitution (1988), in the Mining Code (Decree-Law 227/1967) and its Regulation (Decree 9.406/2018), and in laws that regulate the different legal regimes governing the development of mineral wealth.

The main environmental problems associated with bauxite mining are related to the rehabilitation of mined-out areas and the disposal of tailings. Emissions of dust consisting of clay and bauxite particles from dryers’ chimneys can also pose problems. Brazil’s largest bauxite mine, the MRN mine in Oriximina
The FundГЈo tailings dam was constructed and owned by Samarco MineraГ§ГЈo SA, a mining company, near Mariana, a municipality 67 kilometres (42 mi) southeast of Belo Horizonte, in the state of Minas Gerais, Brazil. The tailings dam was built by Samarco to accommodate the waste resulting from the extraction of iron ore taken from extensive hazards associated with handling and disposal of radionuclide-bearing REE ores and tailings should in theory be regulated adequately by existing EU regulation. This report therefore examines the current EU regulations in terms of their application to REE mining and processing, and evaluates the extent
Considering the actual period of time the hazards from uranium mining and milling wastes persist, these regulations are of course only a compromise, but they are a first step, at least. Regulations for the protection of groundwater were not included in the initial legislation; they … Tailings incidents involving Manila Mining in Surigao City, Philex Mines in Baguio City, Maricalum Mining in Sipalay Negros Occidental and the Marcopper in Marinduque in 1996, where tailings embankments failed, while accidental or unintentional, have nonetheless resulted in the discharge of tailings into marine waters.

The increasing number and size of tailings dams around the... Dewatered stockpiling (dry stacking) is a safer alternative to tailings dams (Rico et al., 2008, [3]) for tailings disposal; however, this method has not yet been used in iron ore mines in Brazil, where geotechnical conditions and abundance of water are favorable for the use of tailings dams.
