Brazilian regulatory framework for NORM in mining and

In Brazil, mining and milling facilities are subject of regulatory control from environmental regulatory agency and from National Mining Agency. Beyond environmental and mining control, facilities that process NORM, must also be licensed or authorized by CNEN, that distinguishes two distinct types of NORM facilities: nuclear and conventional

ACID ROCK DRAINAGE IN THE URANIUM MINING AND

2004-12-23  The uranium mine and mill site is located at the Pocos de Caldas plateau, southeast region of Brazil. The uranium enrichment in Pocos de Caldas mine is related to hydrothermal events (primary mineralisation) and to latter weathering processes (secondary mineralisation). The mining and milling facilities began commercial operation in 1982.

Environmental impact assessment of uranium mining and

1995-1-1  In Brazil the Uranium Mining and Milling Facilities ( UMMF) of Pos de Caldas, Minas Gerais state, began operation in 1982. Since then many scientific studies have been devel- oped. The contribution of waste rock piles as sources of pollution by radionuclides to the surface waters of Pos de Caldas region was pointed out by Amaral et al. ( 1988).
