crushing 2000 lbs of ore to 25 gal (250lbs) should not have any effect on the au oz per ton. some thing is missing. what happend to the 1750 lbs of ore?
what was the head ore au oz per ton? what was the 25 gal au oz per ton?
just grinding an ore should not change the au oz per ton at all. was there any other process used?

The grinding operation is just that.
You must handle the mill use, clean thoroughly before and after grinding.
But during the milling produces a better distribution of gold in the material.
In most of the buying of gold ore sample for analysis was screened to 200 mesh.
The gold particles retained on the mesh errors in the analysis called nugget effect in Spanish.
The analysis of a gold ore must contain a screening at 200 mesh (74 microns).
The decrease in weight of the material probably occurred in a concentration that has returned in the recovery of gold.
I recommend a balance of physical gold that you specify.
A metallurgical balance determines the total amount of gold which has a certain amount of material.
For the most appropriate measurement system (g / t).
An analysis of gold can 25grs/ton.
5 Tons of this material have a total of 125 grams.
Any amount of gold bearing material to be processed must be an analysis of initial gold.
At the end of the process, the initial gold must be distributed in fractions of the total weight.
The amount of gold or retrieved usable is always less than the initial and the term recovery is employed.
