| dc.description.abstract | A method of concentrating iron in laterites to make the iron extraction process economical
is disclosed. Concentration using biomass yields higher levels of iron by using appropriate
ratio of biomass: laterites. The concentration of iron in the laterites was done by heating
a laterite/charcoal mixture in the temperature range 500-700oC in a ceramic container, a
slow current of air (0.5- 0.7cm3/sec) was passed thus generating carbon monoxide in-situ.
The process involves cooling and picking iron containing mineral. The optimum ratio of
biomass: laterite was found to be 1:20 by mass. The iron in the raw laterites is
predominantly minerals goethite, FeO.OH and haematite, Fe203, as shown by presence
of peaks at diffraction angles of 20 = 21.51 ° and 20 = 54.11 °respectively. After magnetseparation iron was present predominantly as the mineral, magnetite Fe304, with
diffraction peak at 20 = 36°. The percentage of iron in the magnet-separated product is
increased to 55-62%. | en_US |
