Sampling for Assaying - Mineral Processing & …
Sampling is the most important procedure in arriving at the value of an ore. Improper sampling makes other procedures, including assaying, valueless, as the sample must truly represent the ore from which it is taken. Before sampling, clean fresh faces must be exposed in order to prevent the possibility of salting. Having taken a large representative sample by chiseling 3″ to 6″ wide and 1 ...

Ray Grimmer Lab Service - ASSAY FAST
Shipping of Sample: The best way to send a sample to us is through the U.S. mail, directly to our P.O. Box. The USPS "Flat Rate" boxes are recommended as the most economical and fastest method. Sample Quantity: An ore sample of a minimum 8-ounces is preferred, for best results. Concentrates: a 3-ounce sample will be sufficient.
UNREALISTIC EXPECTATIONS OF ASSAY RESULTS
Good sample preparation practice at all of these stages is essential to obtaining meaningful and reliable analytical data. An accurate assay is of limited value if the sample preparation has not been carried out to the same standard. Taking gold as an example, over the past decade, sample preparation techniques have improved significantly.
