Iron Ore Beneficiation Introduction. Iron Ore Beneficiation increases the grade of iron whilst maximising recovery and reduces the content of ultrafine low grade slimes to maximise return on investment from the mining process prior to sale or further refining in the iron making process.
Challenges associated with beneficiation include skills and power shortages, limited access to international markets, inadequate infrastructure and working capital constraints.
Wright iron ore mine in Canada. In 2011, we delivered 5,760 spiral starts and in 2014 we delivered an additional 2,688 iron ore spiral starts to the mine. These represented the largest delivery of iron ore spirals to any one mine site. To meet Mont Wright’s specific beneficiation requirements, we embarked on an extensive research.
