The amount of tailings that remain is controlled by what grade the ore is, meaning the percentage of valuable minerals in the ore. For example, if the grade of an ore is 1 percent copper, 99 percent of the total ore would be deposited as tailings. This is based on the number of localities entered for mineral species and is therefore slanted towards minerals interesting to collectors with less coverage of common rock-forming-minerals so it does not give an undistorted distribution of Gold mineral species. The occurrence of gold mainly depends on temperature, pressure, pH values, Cl − concentration, and fugacity of H 2 S in a hydrothermal system. In its natural form, Gold contains traces of silver, as well as traces of iron and copper. For example, today, just one ounce of gold sells for nearly 1,200 dollars.
