抄録

This investigation was undertaken to observe the reducing speed between Fe and Ni, and condition of Ni preferential reduction. We have experimented on reduction of nickel ores by a rotary kiln and measured composition of materials, atomosphere, and its temperature at several points in the kiln.<BR>(Fe Ni Mg) Silicate was reduced slowly and its reduction was done just: before melting point, but neither M. Fe nor M. Ni was produced below about 1, 000°C.<BR>Assuming the ratio of M. Fe to M. Ni between 1, 100°C. and 1, 400°C., we obtained as follows<BR>kFe-Ni=0.0324e0.00295T<BR>therefore we have been able to conjecture condition of Ni preferential reduction in the kiln.
