Grade Blending for Iron Ore Processing Akumen

Blending on the coarse ore stockpile happens according to a user-specified recipe. In other words, the user specifies a percentage for each pile that is converted into a rate at which the pile is drawn down. This allows balancing out periods of low or high grade by blending in stocked ore.

Sintering Properties and Optimal Blending Schemes of Iron ...

2012-6-1  According to the analysis of each ore's sintering properties, an ore blending scheme (Chinese concentrates 20% + Brazilian ores 40% + Australian ores 40%) was suggested. Moreover, sinter pot test using blending mix was performed, and the results indicated that the ore blending scheme led to good sintering performance and sinter quality.
