Discussions of X RAY Data of Reduced Magnetite
by John V Milewski PhD
Rev June 16, 2007
These x ray tests were run at North Carolina State University Graduate School of Ceramics in 1996.
Three separate samples of magnetite grade mag pit ore (MPO) from near Silver City, New Mexico, were run at elevated
temperatures using three different reducing agents.
The first used hydrogen at 1100 C for one hour.
The second used Aluminum in the Thermite process—estimated temperature above 2000 C.
The third used carbon at 1100 C for one hour.
Each set of data is presented in two pages. One gives the raw date for peak intensity vs. 2 theta. The second page
has the numerical data giving the theoretical and actual two theta values, the crystal lattice D spacing, the
theoretical and actual peak heights, the reflecting planes and the compound formula.
The area under the peaks can be used as a rough means of calculation of the relative proportions of each compound
found.
The compound (FeRh)1.8 Ir.2 was found in all three experiments in an estimated 5% to 15% range. That represents a
fair amount of rhodium and iridium in the original black sand. Calculations made using atomic masses and atomic
percentages gives the following compositions for this compound, 57.3% Rh, 11.7% Ir, or 69% of these platinum group
metals (PGMs) in this compound that came from this black sand magnetite. I believe that these PGMs were originally
in the ormus, non-detectable form before their reducing compound heat treatment that reformulated their atomic
structure to the new metallic formed compound.
The support for this idea is that this MPO magnetite was previously sent out and given a nuclear resonance
spectrographic analysis for PGMs and they showed no Rhodium or Iridium with a detection limit of less than 5 ppb
(that's parts per billion). This new data is pretty good information proving the presence of rhodium and iridium in
this type of magnetite.
The highest yield of the rhodium, iridium elements comes out to be about 10% of the magnetite. This was found in
the Thermite reduction process which uses aluminum as a reducing agent. This higher yield is probably due to the
fact that this process ran at a very significant high
temperature.
