【 摘 要 】

Mining planning and its correct sequencing are essential to facilitate the exploitation of minerals both economically and environmentally, thus ensuring the feasibility of the mining in operational and economic terms. The small geological complexity or the low aggregate value of a mineral deposit tends to result in the planning stages being neglected, so the mining begins without the necessary detailing or it is only scheduled for a short period of time. Thus, in order to ensure a sustainable sequence of operations, and to predict the environmental impacts caused by mining activities and suggest options that would allow the establishment of mitigation measures for these impacts, the feasibility of the technical and economic utilization was evaluated for an occurrence of bentonite in the Bañado de Medina deposit located in the Department of Cerro Largo, Uruguay, respecting the local environment in the process so as to give the project a strong character of sustainability.
