UPGRADING OF Mn / Fe RATIO OF LOW-GRADE MANGANESE ORE FOR
electric furnace. Huge amounts of low-grade manganese ores are located in many countries around the world. These deposits are only partially used in ferromanganese production. The ores contain large quantities of iron and thus the Mn / Fe ratio is low, 3
It ensures a homogenous output towards the beneficiation plant and avoids the processing of low grade ore or waste. Our solutions can be employed for continuous, non-contact monitoring of elemental and mineralogical composition as well as the prediction of process relevant parameters in a large range of mining applications such as iron, bauxite, copper, nickel or coal.

What Is Iron Ore Beneficiation? (with pictures)
Low-grade iron ore includes all mixtures below 62% iron concentration, which are not considered to be viable types of ore for use in metallurgy. Several different types of natural iron ore exist, but the two most common types used for metal refining are hematite , Fe 2 O 3 , which is usually 70% iron, and magnetite , Fe 3 O 4 , which is 72% iron.
