Iron ores [1] are rocks and minerals from which metallic iron can be economically extracted. The ores are usually rich in iron oxides and vary in color from dark grey, bright yellow, or deep purple to rusty red. The iron is usually found in the form of magnetite ( Fe. 3O. 4, 72.4% Fe), hematite ( Fe. 2O.

Feb 11, 2015· 1) Blending (homogenisation) effort is combination of blending ratio and batch size. 2) Blending ratio is defined as (Standard deviation input) ÷ (Standard deviation output). The smaller the batch size, the more will be the blending (mixing) effort. Also, more blending ratio means more is the blending effort.
