What is Metallurgical Assay?
Mineloans.com offers prospectors gold mine loans. While many requirements must be met, including geological reports, executive business plans, permits, claims and financial information, Mineloans.com also requires assay reports.
Assay reports are specific to the raw mineral industry and they are an analysis of alloy, ore or metals. Different assay methods are used depending upon the materials and whether they are raw or finished.
Gold is generally assayed using platinum and cupellation by a technique that uses inductive coupled plasma optimal emission spectrometry. Jewelry, art and other precious metal figures are assayed, or hallmarked, using tests that analyze metals’ contents. The assay test simply determines the fineness of metals’ qualities, ensuring that 24K gold is actually true and accurate. Gold stocks and bullion are generally subjected to a cupellation or fire assay, which tests for metals’ exact purities.
Jewelry and other fine, valuable pieces are often subject to red radiolarian chert tests, which highlight precious metal contents. It should be noted that this method is not sufficient for testing white gold.
X-ray fluorescence is also non-harmful to precious objects and has an accuracy rate between two to five parts per thousand. This method works particularly well with large surfaces or flat objects. This method includes a computer analysis and only takes approximately three minutes to complete.
Destructive, yet extremely accurate, fire assay testing is the standard for gold mining companies and major refineries. A significant reason why these major producers use fire assay methods is because they can further increase metals’ accuracies, which can yield low ore concentrations levels that are <1g/T.
Assayers once played a critical role in coinage, as they would determine the purity of each coin produced. This was particularly relevant when mint offices circulated gold or silver coins, but the U.S. discontinued gold coinage in 1933. The U.S. Mint still produces coins for investors and collectors and the assayer process guarantees these valuable, collectable coins.
