Utah Gold Prospecting; ... but the gold is also recovered as a byproduct during processing of the ore. Most byproduct gold has come from porphyry deposits, which are so large that even though they contain only a small amount of gold per ton of ore, so much rock is mined that a substantial amount of gold is recovered. The largest single source ... The amount of gold per ton of ore is generally how the value of a hard rock ore body is evaluated. Some high-grade free-milling ores that have visible gold veins running through quartz may run as high as an ounce or more in gold for each ton of rock, however most gold ores are considerably less than that.

Ore is stockpiled (1) at the processing plant, and the process begins by feeding the ore into a hopper with a loader. The ore is conveyed, and lime is added (2) to raise the pH of the ore. Following crushing through a jaw crusher (3), the ore is fed into the semi autogenous grinding (SAG) mill (4) along with water and steel balls. Gold production declined and many gold mines closed during World War I (1914-1918) due to a shortage of manpower, decreasing ore reserves, and increasing costs. During the depression in the early 1930s, gold mines were brought back to life and prospectors thoroughly searched the known and little-known gold-producing areas.
