  Processing High-Grade Concentrates from Challenging Low-Grade Iron Ore ...

  201373 · 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 …

  Determining Iron Grades of Ores or Concentrates Containing …

  2020218 · In this study, a new method to determine the iron grade in iron sulfide ores was proposed by using perchloric acid. The iron grade of a high pyrite-containing ore was determined by the new method, and the results were compared to those obtained by the traditional roasting or HNO 3 titration.

  Ore-blending optimization for Canadian iron concentrate during iron ore ...

  2019925 · Canadian iron concentrate (CIC) can elevate the ferrous grade and lower the contents of gangue components and harmful elements in the sinter. To understand high-temperature characteristics of CIC and typical iron ore, the formation of the melt was calculated mainly through FactSage 7.2, and melt fluidity (MF) test for iron ore fines and …
