how iron ore is exploited

Minerals

The iron ore mines located in Latin America are large reserves and high quality. In countries like Brazil, Mexico, Peru and Chile mines are exploited by small miners who live in this work. In order to do business with significant amounts, these miners were grouped in different associations or cooperatives that collect iron ore and is responsible for negotiating.
