Been meandering around in the swamp which is clay-hosted REEs for a week or so and came across this release. A question about the data...
The way I read it the table below says:
- samples were assayed
- samples were split into two about 45 microns
- the stuff less than 45 microns was assayed
- the grades were higher in the small stuff, YAHOO!
As to how much of the feed REOs ended up in the -45 micron fraction, well no-one seems to care less!
You've got the recovery column which I believe is the percentage of feed reporting to the -45 micron fraction.
Now REO recovery = -45micron REO / (Head REO / recovery%)
Using that formula on say hole CBAC22-200 gives 1902 / (1198 / .62) = 98% of REOs reporting to -45 microns YAHOO again
However if we do the same to CBAC22_183 we get 905 / (433 / .49) = 102% of REOs so more than went in came out
There are numerous other examples in the list.
What have I missed?
