Abstract in Portuguese
Melhorar o conhecimento sobre o minério lavrado é um desafio enfrentado diariamente pelas empresas de mineração. O presente trabalho trata de um estudo realizado na mina de apatita, localizada na cidade de Cajati, interior do Estado de São Paulo, de propriedade da Bunge Fertilizantes S/A, onde são abordados temas relacionados ao planejamento de lavra de curto prazo, visando o aprimoramento dos procedimentos de coleta de amostras de pó-de-perfuratriz, que são sistematicamente coletadas com o objetivo de controle de qualidade da lavra, contribuindo para uma efetiva melhoria na gestão do planejamento de lavra e na tomada de decisões. Os resultados obtidos mostram que, da forma como as amostras são coletadas, ocorre um enriquecimento do teor de P2O5, podendo levar a tomada de decisões erradas por parte da operação da mina.
