CURI, Adilson e LAGE, Edson Rogério. Avaliação econômica do minério remanescente nos taludes da cava final da Mina de Alegria. Rem: Rev. Esc. Minas [online]. 2003, vol.56, n.1, pp.41-44. ISSN 1807-0353. http://dx.doi.org/10.1590/S0370-44672003000100008.
This paper introduces estimated benefits, obtainable by use of "cut and filling" mine-methodology extraction of ore remaining in slopes of the final pit in an open pit mining operation. The economic viability of this method considers product market value and operational costs. When terminating a mining operation, the generation of additional revenue is highly desired, since it implies unforeseen economical earnings. This also holds true for already-closed mines. When the method desribed in this study is used, there is also an environmental bonus since there is no waste pile construction.
