Hence, the sample was initially separated by low intensity wet drum magnetic separator (LIMS) supplied by Sala International, Sweden to separate magnetite portion at different particle sizes. The sample was ground to −210 and −100 μm and subjected to Sala LIMS.
Manganese mineral is a weak magnetic mineral ( the specifical magnetization coefficient x=10×10-6～600×10-6cm3/g ), and it can be recovered in a strong magnetic field magnetic separator with a magnetic field strength Ho=800～1600kA/m (10000～20000oe), the manganese grade is increased by 4% to 10%. The magnetic …
By eliminating non-magnetic contaminations, this framework is used to focus on magnetic metals of iron including magnetite and chromite and manganese (pyrolusite). A magnetic separator is used in this system. An attractive separator is built from rollers and a cowhide based belt. One of the 2 rollers has a magnet implanted in it.
Siliceous manganese ore, associated with the banded iron formation occurs in large volume in northern Odisha, India. It is a sub-grade ore containing 21% Mn, 60% SiO 2 and 3% Fe, hence do not find any use and considered as waste. Such ore does not respond to any physical beneficiation techniques because of intricate microstructure and poor liberation …
