ore at a mining plant requires the routine analysis of various samples. These include the feed (crushed ore), the tails (waste ore after processing) and the concentrate (final product). For a copper-gold mine, the metals that require analysis can include, not just copper (Cu) and gold (Au), but also silver (Ag) if present at significant levels.

For example, lets say that a mine was processing ore valued at 1 troy ounce of gold per ton. This would generally be considered a very high-grade ore, worth mining in most cases. Using this hypothetical value of 1 ozt./ton, each pound of ore would contain approximately 0.0005 ounces of gold. Now let’s assume that gold is valued at $1500 per

The chemical composition of native gold and electrum from auriferous vein and gold-silver vein deposits in Japan has been analyzed and summarized. The Ag/Au ratios of native gold and electrum from these two types of deposits are distinct, i.e., 10–20 Ag at % (auriferous vein) and 30–70 Ag at % (gold-silver vein). Thermochemical calculations suggest that the Ag/Au ratio of native gold and

Gold doré bars commonly come from two sources; mines or reclamation scrap. Mines almost never excavate pure gold ore. Most ores contain a mixture of gold and other useful base and/or precious metals. Silver for example is one of the precious metals most often found with gold ore, so a doré bar will often be made primarily from these two metals.
