Diagnóstico na geração de rejeitos da indústria de mineração de calcário agrícola no estado do Tocantins

Abstract

In the State of the Tocantins, the enterprises of mining from Limestone appear like one of the most relevant from the point of view of the mineral economy and of the generation, in volume, of solid residues. The control and maintenance of the production and destination of solid residues in Brazil happens, firstly, through auditing of the informations given annually by the creator near the Federal Technical Register of Potentially Pollutant or Usufructuary Activities of Environmental Resources – FTR/PPA, in which it has approximately of three million set up extern users. To administer the informations that all these users produce annually in the system has when if an important challenge was demonstrated to the organs of control and inspection. Having in mind this problematics, the present work aimed at the realization of a diagnosis of the generation of mining reject between 2010 and 2014, from the relation between values of brutish production and beneficial production informed by the enterprises of mining from agricultural limestone of the Tocantins. Subsequently, there was carried out the crossroad of the values of generation of mining reject obtained in the diagnosis with those informed by the enterprises of mining near the FTR/PPA. Of this crossroad deficiencies of the system were identified and new parameters were indicated for auditing of the informations given by the enterprises near the FTR/PPA, which, if implemented, can reduce significantly the institutional effort for the fulfillment of his paper of inspection and environmental control.
