What is a vein in mining?

Hematite and magnetite are by far the most common types of ore. Pure magnetite contains 72.4 percent iron, hematite 69.9 percent, limonite 59.8 percent, and siderite 48.2 percent, but, since these minerals never occur alone, the metal content of real ores is lower.

How much gold is in a vein?

These veins form in rock fractures, but their formation has always stubbornly eluded explanation . The concentration of gold in the veins is simply too high to explain by the crystallization of the gold out of dissolved hydrothermal fluid. These fluids can hold only 10 to 30 parts per billion of gold.

Does gold run in veins?

Gold may occur as deposits called lodes, or veins, in fractured rock. It may also be dispersed within Earth’s crust. Most lode deposits form when heated fluids circulate through gold-bearing rocks, picking up gold and concentrating it in new locations in the crust.
