The ratio between ore and vein minerals varies greatly, depending on the metal and the given deposit. For example, in veins of gold-bearing quartz the amount of gold relative to the mass of the quartz is thousandths of 1 percent. On the other hand, some types of iron ore consist entirely of ore mineral (magnetite, hematite).

2020-1-12  History . Iron was likely originally discovered and extracted as a result of wood burning on top of iron-containing ores. ﻿ ﻿ The carbon within the wood would have reacted with the oxygen in the ore, leaving behind a soft, malleable iron metal. Iron smelting and the use of iron to make tools and weapons began in Mesopotamia (present-day Iraq) between 2700 and 3000 BCE.
