Iron Ore Beneficiation Technology. Almost all of the iron ores are used in steelmaking. Iron ore is mined in about 50 countries. Australia and Brazil together dominate the world's largest iron ore exports, each having about one third of the total exports. The banded iron formations are found throughout the world and are the most important iron.On 25 January 2019 it happened again. Just three years and two months after Samarco’s tailings dam failed, the world’s largest iron ore producer, Vale, saw one of its tailings dams collapse in Brazil. Administrative buildings and infrastructure were destroyed as 11.7 million m3 of mining waste from ore processing, also known as tailings, flooded the site.

Each primary mill contains several 4 steel balls that grind the ore as the mills turn.Vale has 19 iron ore mines and 10 industrial beneficiation plants in the QF region. These produce almost 200 million tons per year of iron ore, which represents approximately 70 of the total production in the region (DNPM, 2012 Vale S.A., 2012). Production is forecast to increase approximately 10 between 2013 and 2017, and 50 by 2030.
