How We Analyze
Your Scrap

It is our goal to recover the highest possible amount of gold, silver, platinum and palladium from your scrap material. Our leading-edge laboratory offers a variety of analytical techniques that are capable of detecting even the smallest amounts of precious metals. After your bullion has been weighed, drill samples are taken from each end and fire assayed in duplicate to determine the precious metal content. The results of the assays must agree. If they do not, the bar is remelted to ensure that it is homogeneous and then resampled and reassayed.

 

ANALYTICAL TECHNIQUES USED AT HOOVER & STRONG

 

XRF: X-Ray Fluorescence Spectroscopy (XRF) is a non-destructive technique capable of determining the concentration of multiple elements within a sample. It is particularly useful for providing quantitative and qualitative results in a very short amount of time, but it is the least accurate of our 3 available techniques. Our XRF spectrometer cannot determine elements lighter than aluminum. The most accurate results are obtained from smooth, flat, homogenous samples.

 

 

 


FIRE ASSAY: Arguably the most accurate method for determining gold content, this ancient technique is still used today. A small amount of your sample undergoes a systematic thermal and chemical process to determine the concentration of precious metals. Samples must be homogenous for accuracy.
