Propostas metodológicas para quantificação mássica de pilhas de minério de ferro

Abstract

In the process of stock inventory of iron ore mines, the accountable stock is adjusted by measuring the physical stock. The volumetric physical stock is estimated by topographic procedures and converting the values obtained into mass using the ore pile bulk density. This study aims to describe nowadays most used methods to assess the geometry and to estimate the mass of iron ore piles and to show the author's view about the benefits, constraints and difficulties in applying these methods. This work also aims to describe the main variables that influence the determination of pile mass and to present other methodologies to estimate the bulk density of piles for measuring the physical stock piles of iron ore more precisely.
