Principais etapas do tratamento de minérios itabiríticos do Quadrilátero Ferrífero

Abstract

The iron mining industry has the requirement to provide concentrates within the specifications of the metallurgical industry. However the major deposits of iron ore existing in Quadrilátero Ferrífero show an increased presence of itabirites. So there is a tendency to treat ores with a liberation degree only achievable in a very fine particle size and also with low iron content. The mining industry must adapt its main techniques, methods and equipment applied nowadays to attain this new challenge in the iron ore deposits.This paper aims to briefly review the main stages of iron ores processing.The descriptions of the stages of crushing, grinding, classification, concentration and solid-liquid separation applied in the beneficiation of fine iron ore were made from the citations and references found in the literature.The correct selection and use of equipment makes possible for the mining industry an adequate itabirite beneficiation.
