Assaying, in chemical analysis, process of determining proportions of metal, particularly precious metal, in ores and metallurgical products. The most important technique, still used today, grew largely out of the experiments of the ancient alchemists and goldsmiths in seeking to find or create precious metals by subjecting base metals and minerals to heat.
When gold dissolution is complete, the goldbearing solution is separated from the solids. With ores of higher gold content (greater than 20 grams of gold per tonne of ore), cyanidation is accomplished by vat leaching, which involves holding a slurry of ore and solvent in large tanks equipped with agitators.

Apr 14, 2020· Smelting and assaying a sample of high grade gold ore and comparing to the gold panning results in part 1, we determine how much gold was liberated by crushing and panning vs assaying. The lead ...
Fire Assay Collection: the most usual process for gold is traditional Fire Assay by cupellation (following ISO 11426). This test is accredited to UKAS 17025. This requires small samples of gold to be carefully weighed before being wrapped in lead foil together with a predetermined quantity of silver.
Screen Fire Assays (SFA500SFA1000), for quantifying gold in coarse samples. Geochemical Metallurgical Testing Fire Assays (FA25, FA30, FA50), for quantifying gold in noncoarse ore AAS, ICPOES and LECO® analysers for quantifying carbon and sulfur content, gold on carbon, gold in solution and for laser sizing of metals in ores.
Durable equipment and accessories for every stage of the fire assaying process While the basic fire assay technique for the recovery of gold from precious metals has changed very little over the past two thousand years, our fire assay systems and accessories bring many new efficiencies to .
Testwork on screen fire assays, duplicate assays and fire assay to extinction has demonstrated assay variability associated with coarse, particulate gold. The variability and distribution of gold in Tarmoola ore types has emphasised the importance of high quality sample preparation for leachwell assaying to ensure liberation of gold to leaching ...
Fire Assay For Gold. The Gold Fire Assay Process of ores is almost universally conducted in the dry procedure by furnace methods Exceptions will be noted later The plan of operation is to concentrate the precious metal in a button of lead either 1 Fire Assay By fusion in a crucible or more rarely 2 Fire Assay

An assay is an analysis of raw ore or refined metal to determine the presence, absence, or quantity of one or more components. Refined precious metals, like gold silver and platinum are assayed to test the purity of the metal. Investment decisions are often determined by assay results.

We offer a "Fire Assay" service to ensure you are provided with the most accurate result possible for identifying the precious metal content of your refining or metallic sample. We only offer our assay service for Metallic samples – WE DO NOT ASSAY ORE SAMPLES.
The cupels are removed from the furnace, allowed to cool and the gold bead is weighed. The most common unit of fire assay samples is called the Assay Ton, which is grams of ore. A milligram () gram of gold in a sample weighing grams gives an assay equivalent to 1 troy ounce of gold in a ton (2,000 pound) of ore.
The book includes information in technical terms and general terms so readers can comprehend the process of melting metals and processing ore through a fire assay. Very helpful information on how to mix fluxes, prepare your crucible, melt gold and silver, and how to stay safe doing it.

A metallurgical assay is a compositional analysis of an ore, metal, or alloy.. Some assay methods are suitable for raw materials; others are more appropriate for finished goods. Raw precious metals are assayed by an assay is assayed by titration, gold by cupellation and platinum by inductively coupled plasma optical emission spectrometry (ICP OES).
