Why the grinding require of iron ore

Update date: Dec 28

Uwadiale (1990a) used selective oil agglomeration to upgrade Agbaja oolitic iron ore from a feed value of 45.6% Fe to a concentrate containing 65% Fe at 89.3% Fe recovery. The ore was very fine grained and ultrafine grinding ( 5 m) was required for liberation. The main iron mineral was goethite with minor hematite and maghemite

    Jan 01, 2015 Iron ore grinding and classification. Compared to direct shipping hematite ores mined from the upper regolith, magnetite deposits are much finer-grained and therefore require significant grinding to liberate the magnetite from its silicate matrix. Various magnetite ore grinding flowsheets have been implemented in the past, including

    For example, the extraction of 1 ton of lead from 30% grade ore by smelting requires almost 1.3 more energy than to extract the same quantity of Pb from 60% grade ore. Besides, in the grinding section, there is a tip to reduce energy consumption. As far as the ore requires fine liberation, more energy for further grinding is needed
