Gold and silver are obtained from a variety of ores, in some of which the gold predominates, in others silver is the primary value, while in still a third class these two metals may be mixed with the base metals, such as lead, copper, zinc, and iron.
Platinum represents one of the rarest metals on Earth. Seldom occurring on its own, it exists with other metals in the Platinum Group Elements (PGEs): rhodium, ruthenium, palladium, osmium and iridium, and occasionally alongside gold and diamonds. Platinum can be found in alluvial placer deposits in flakes or in small grains.

I could argue that gold production is too low, and its price even more suppressed compared to silver." No, with the gold/silver ratio still at close to 70:1, and the normal, rational, PHYSICAL relationship of the two metals at around 15:1, it is impossible to argue that the price of gold is too low versus silver.
Platinum is the rarest of the precious metals. Platinum was discovered by astronomers Antonio de Ulloa and Don Jorge Juan y Santacilia in 1735. Charles Wood independently isolated the element in 1741. Approximately 8 tons of raw ore must be mined to produce just one pure ounce of platinum. Roughly 90% of all platinum supplies come from South ...
Gold is usually found alone or alloyed with mercury or silver, but can also be found in ores such as calaverite, sylvanite, nagyagite, petzite and krennerite. Most gold ore now comes from either open pit or underground mines. The ores sometimes contain as little as 5/100 of an ounce of gold .
Other large-scale, industrialized ore-milling methods had been implemented in silver-mining districts beyond the Comstock, but the Washoe Process consumed the least amount of energy—an attribute essential at Bodie, where the ore contained silver as well as gold, and which was isolated from a .

In most gold ores, the final process to extract the tiniest gold particles is the use of cyanide to dissolve the gold. Cyanide, in the presence of oxygen actually dissolves both gold and silver. It is both efficient and inexpensive, so it is widely used in precious metal ore processing.
The fourth class of gold ores comprises the gold-telluride group. The gold telluride ores occur with silver, or with silver, lead and antimony, or as native gold accompanied by other tellurides. These ores are often sent direct to the smelters for treatment. A fifth type is the disseminated ore type. They are often low in grade but large.
