The dry processing is related to the quality of the iron ore extracted on the mining front. In Carajás, as the iron content is already high (above 65% iron), the material is only crushed and screened to be classified by size (granulometry). In Minas Gerais, in some mines, the average content is 40% iron.
Carajas iron ore mine expansion. In 2007, Vale approved an expansion project of the Carajas mine. The $2.48bn project, Carajas 130, would add 30Mtpa to the current capacity of 100Mtpa. In 2009, $798m was diverted towards the project. ... The project featured innovative solutions including truckless system and dry processing.
increase dry processing for years. Over the last decade, the company invested almost US$17,8 billion to deploy and expand the dry - or natural moisture - processing of the iron ore produced in Brazil. Over the next five years, we estimate to invest US$3.1 billion in similar processing facilities to achieve the goal of 70% of dry production.
The S11D project entails installing an iron ore mine and processing plant, with three production lines - each one able to process 30 million metric tons per year. The ore will be extracted through open-pit mining and transported from the mine to the plant by a long-distance conveyor belt.
US Steel initially wanted to develop the Carajás iron deposit alone, but the Brazilian Government was unwilling to hand control over to a foreign company. In 1970, the Brazilian Government opted instead to create a joint venture company, Amazonias Mineração (AMZA), which 51% was owned by Vale and US Steel ha…
