high grade iron ore processing

Processing High-Grade Concentrates from Challenging

2013-7-3  On an average global basis, iron ores tend to decrease in Fe grade over time. With the exception for some deposits that are logistically challenged, iron ore resources in more accessible areas may often have processing issues, especially if high-grade concentrates are desired. This paper addresses some of these with examples on how technological developments enhanced the feasibility
