Gunnison County, in west-central Colorado west of the Continental Divide, produced about 130,000 ounces of gold through 1959. Although the first ore discoveries were placer deposits, most of the gold produced in the county has been a byproduct of silver-lead ore. Ore was first discovered in 1861 when placer gold was discovered simultaneously ...
E. 2.50. Show Spoiler. Since the 50-pound sample of ore is 5 percent metal, then there are 5% * 50 = 2.5 pounds of metal in the ore. Since those 2.5 pounds of metal consist of 10 times as much silver as gold, assuming the weight of gold is x, the weight of the silver will be 10x. Hence, we have x + 10x = 2.5.
Gold Ore Processing. Carbon-in-pulp (CIP) consists of cyanide leaching and then absorption of gold from ore, which is considered a simple and cheap process. Using a CIP gold processing plant, pulp flows through tanks where sodium cyanide and oxygen help dissolve gold into solution. CIP plants are similar to Carbon-in-leach plants.
Gold ore can be obtained in various ways. It can be smelted into bars of gold ingots. Gold rocks naturally generate on the Buffalkor Island,Emerald Mines and the Diamond Mines. Mining a gold rock yields 2 - 3 gold ores per stage, resulting in a total of 4 - 6 gold ores. There's also a 10% chance the rock drops crystallized gold. Gold rocks used to spawn …
Quite often the gold in an ore is tarnished, or as it is termed "rusty". This brownish tarnish or coating very often consists of oxides of iron, but black coated gold is not unusual. The effect of such coverings on the gold particles is to retard dissolution and usually to increase the gold content of the cyanidation residue.

Players who want strictly gold should focus on mining it at the Crafting Guild Mine, …
The sulphide fraction of the ore consists of 3 wt% pyrite and 2 wt% arsenopyrite. The remainder of the ore is made up of quartz, chlorite, sericite and carbonate. A sample of the ore is ground to 80% passing 75 µm, and is subjected to a standard gold cyanide leach test in the laboratory. Gold recovery from this test is 58%.
