In most gold ore, the gold is present in tiny specs, either within minerals like pyrite, or spread out free among the quartz. Normally even good, rich gold ore has no gold metal which is visible to the naked eye. The photo at left shows small particles of metallic gold in quartz taken from the mountains of Canada. Sections of gray colored quartz in the specimen have this appearance because of

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 of byproduct gold in the United States is the porphyry deposit at Bingham Canyon, Ut, which has produced about 18 million troy ounces of gold since 1906.

Gold ore processing. In placer mines, the gold is recovered by gravity separation. For hard rock mining, other methods are usually used. Cyanide process. Cyanide extraction of gold may be used in areas where fine goldbearing rocks are found. Sodium cyanide solution is mixed with finely ground rock that is proven to contain gold or silver, and is then separated from the ground rock as gold
To extract the gold, the ore is crushed, then the gold is separated from the ore by various methods. Gold nuggets, a popular form of Gold with collectors, are formed when erosion causes a large piece of Gold to separate from its mother rock, and then gets carried into a stream or river. The flowing water tumbles the Gold, giving it its distinct rounded shape. The Gold eventually settles at the
Gold ore is a fairly rare ore found in Minecraft. When mined with an iron pickaxe or better, it drops one gold ore. It serves little use in crafting tools because the resulting tools won''t be very durable, a fact often overlooked by players. Gold ore is found deeper than many ores in the game, below layer 30.
