Beneficiation of Iron Ores ispatguru. The process adopted to upgrade the Fe content of iron ore is known as iron ore beneficiation (IOB). However, Iron ores from different sources have their own peculiar mineralogical characteristics and require the specific beneficiation and metallurgical treatment to get the best product out of it.
In consequence, leadfree and lowlead ores command a premium. Although iron occurs in nearly all zinc concentrates from 1 to 2 per cent, up to 10 or 12 per cent., the percentage carried by the zinc is not proportional to the amount in the ore. The penalty on highiron ores is due to other reasons.
Haifeng et al. [62] invented a process for the reductive leaching of manganese from low grade manganese ore in H 2 SO 4 using cane molasses as reductant. The result showed that manganese dioxide ores cannot be leached by the sulphuric acid directly, .

However, Iron ores from different sources have their own peculiar mineralogical characteristics and require the specific beneficiation and metallurgical treatment to get the best product out of it.
Lean iron ores are normally upgraded to a higher iron ore content through beneficiation. This process generates iron ore filter cake which needs to be pelletized so that it can be used in an iron making process. Also during the processing of high grade iron ores which do not need beneficiation, generated fines can be pelletized and used instead ...
