Copper minerals and ores are found in both igneous and sedimentary rocks.
then, Is ore a gold?
Ores. The major ores of gold contain gold in its native form and are both exogenetic (formed at the Earth’s surface) and endogenetic (formed within the Earth). The best-known of the exogenetic ores is alluvial gold. Alluvial gold refers to gold found in riverbeds, streambeds, and floodplains.
hence, How does copper appear in nature?
Natural abundance
Copper metal does occur naturally, but by far the greatest source is in minerals such as chalcopyrite and bornite. Copper is obtained from these ores and minerals by smelting, leaching and electrolysis. The major copper-producing countries are Chile, Peru and China.
indeed What does copper look like in natural state?
Copper is one of a few metallic elements with a natural color other than gray or silver. Pure copper is orange-red and acquires a reddish tarnish when exposed to air.
and What does copper look like in rock?
Copper, is a copper red to reddish-brown, soft, ductile and malleable metal. Its color as copper red is best seen by reflected light.
How much gold is in gold ore? 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 ounce. That would make the gold in a one pound ore sample worth approximately 75 cents, and this is assuming that the ore is extremely rich.

What’s the difference between gold and gold ore?
The Mineral gold. … Much of the gold mined is actually from gold ore rather then actual Gold specimens. The ore is often brown, iron-stained rock or massive white Quartz, and usually contains only minute traces of gold. To extract the gold, the ore is crushed, then the gold is separated from the ore by various methods.
