Recuperação de finos de barragens no Complexo Paraopeba I

Abstract

The monograph shows projects carried and at analysis of the use of fine tailings in mining iron ore as an option to meet the market demand, focusing on the unity of Paraopeba Complex I of Vale.The projects presented here are subject to immediate and innovative actions. In addition to an economic alternative, with profits without huge investments, are choices that allow for the deferral of exploitation of new reserves and environmental benefits.Driven by high demand, favorable price and environmental factors, major mining companies have been investing in the exploitation of ore with low iron content. One source of this ore are mine tailings dams, where during the course of processing the raw material, millions of tons of useful minerals were discarded for these contenders.The lack of historical records was not an impediment but a motivator for creativity and development of technological choices on the part of those involved in planning and operation of mining.The challenge was to learn to take advantage of the difficulty generated in a time of adversity, when decisions on the 2008 crisis eventually generate operational impediments in the resumption of production in 2010.In addition to becoming economically viable projects have proven beneficial to the environment and society.
