12/01/2020· 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. Over the following 2,000 years, iron smelting knowledge spread eastward into Europe and Africa during a period known as the Iron Age.
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

Some forms of gold ore make recognizing its gold content challenging. For example, pyrite and arsenopyrite are carriers of invisible quantities of submicroscopic gold. Another obstacle to seeing gold in gold ore occurs when gold entwines with other metals within the ore. Such finely distributed particles of gold onlye visible after tests reveal the ore is worthy of processing. References
