Raw Gold Composition

Raw gold is a naturally formed high gold content precious metal alloy.  The composition of this alloy is a large percentage of gold combined mostly with silver, copper and lead. In addition there may be other metals, but in much smaller proportions.  Silver, gold, copper and lead are highly related metals.  In fact, they are all mining by-products of each other.  Where there is gold, usually all the other metals can be found as well, but in varying proportions.  This happens the other way around too.  In addition to that, raw gold, specially gold nuggets, contain, trapped in their shape, quarts and other minerals typical of the area where the nugget is from.

Nugget Gold Purity

In our experience, gold nuggets, for the most part, are seventeen karats (17K) in average.  Larger size nuggets, since they are a natural substance, are un-uniform in composition.  Parts of the nugget may be as pure as twenty two karat in purity, with other part very much lower.  The best gold refinery result we have so far obtained from nuggets just over eighteen karat (18K) in purity.  So far we have never seen better.  See refinery result sample below.

Gold Dust and Flake Purity

Gold dust and flakes are very similar in purity to gold nuggets.  However, there is a major difference.  Since the gold nugget is a single unit, is was formed in only one place.  On the other hand, gold dust and flakes are small particles.  Because of this, and because it takes a lot of effort to gather, often, gold dust and flake samples were collected from multiple locations.  However, even like this, most gold dust and flake refinery results are also in the range of eighteen karat (18K).  In our experience, very few gold flake and dust material is higher than 18K.  Since 2009, here at Portland Gold Buyers, LLC, we have bought gold dust and flakes several dozen times, if not over one hundred times.  Of all those times, only two (2) times we bought material that refined at at twenty karat (20K), which is 83% pure.  See refinery result sample blow.

In my experience, raw gold is very seldom lower than 75% pure, or higher than 90%, after all non-metals have been removed.   In this material, a part of the mass is non-metallic.  At the time of refining, that mass will float out of the metal mass.  Because of this, the after melt weight will be a little lower than the pre-melt weight.  It is this mass, the post melt mass, that will be assayed.

Refineries take only pretty clean raw gold batches.  Beyond a very minimal amount of non-metal, most refineries will not take the material, because very soon it qualifies as ore.  Handing ore is closer to the mining process than to the refining process.Natural Gold Nuggets For Sale

Below is a sample of a refinery result.  As you can see, in this very clean sample, there was almost 4% non-metal mater.  That is very normal.

Cash Offers for Raw Gold.  When buying raw gold, I discount the possible amount of non-metal mass, and assume close to 75% gold content.  That is a very fair offer.  Above that, cash offer for raw gold, it may not work out financially or may even be a loss.  For larger batches, it is preferable to handle this via a contract.  Contact me for more information.Natural Gold Nuggets For Sale
