Resumo
This paper aims to evaluate the diesel oil consumption between 2008 and
2015 in the production of iron ore in Brazil, creating correlations between
energy intensity (production), economy and checking the impact of fuel prices
on the commodity. During the analyzed period, the years 2008-2009 indicated
economic crises, which interfered in the price and the commercialization
of iron ore products. The physical intensity was 0.2% higher than the
economic intensity. In the period from 2010 to 2014, economic activity remained
more stable, with a decreasing trend, mainly due to the increase of
iron ore prices. The physical intensity is much higher than the economic intensity
influenced by the expansion of the Chinese economy. The year of 2014
indicated the end of the high iron ore price cycle and the beginning of supply
and demand stabilization with consequent reduction in prices. In 2015, the
market entered the stabilization phase, with a continuous reduction in unit
production costs and transportation logistics. There was an abrupt change
due to the strong increase of the economic intensity due to the fall of the
international prices of iron ore. The diesel oil consumption plays a vital role
in the scenario of cost reduction in iron ore production and a deeper analysis
must be done in order to discover some options to change the energy
matrix.
