Simulation of wet ball milling of iron ore at Carajas,

2007-10-19  Brazil has one of the largest iron ore reserves in the world, including an estimated 17 billion tons of high-grade iron ore located in Carajas. The formation originated from jaspelite; according to the currently accepted theory, the ore bodies were formed from meteorological alteration of the jaspelite, leaching out the silica and enriching the hematite horizons.
