Geochemistry of hydrothermal gold deposits: A review

2011/7/11. Introduction Ore deposits are the product of crustal evolution in specific areas and at particular stages. Hence, a full understanding of the local geological setting is a prerequisite in studying the genesis of ore deposits (Hedenquist and Lowenstern, 1994, Simmons and Brown, 2006, Zhu et al., 2007b, Hou et al., 2008, Baker et al., 2010).

The Discovery of Metals

Gold, Silver and Copper are all examples of Native metals that naturally occur in a relatively pure state. Ancient man first found and began using Native Metals approximately 5000 years BC. Over the next 2000 years, leading up to the Bronze age, man mastered how to find, manipulate and use these native metals in better ways and in a range of applications. Get price

The metal was found in Massachusetts in 1628 and later, a company was formed to work it in 1643. Rhode Island, Connecticut, New York, and Pennsylvania followed suit.

Iron

Iron ore is the raw material used to make pig iron, which is one of the main raw materials to make steel. Raw iron is alloyed with a variety of elements (such as tungsten, manganese, nickel, vanadium, chromium) to strengthen and harden it, making useful steel for construction, automobiles, and other forms of transportation such as trucks, trains and train tracks.

The Nevada Silver Rush

2019/1/27The climate of Nevada concentrated this silver ore in supergene enrichment. These heavy gray crusts were often polished by dust and wind to the dull luster of a cow horn—horn silver. You could shovel it right off the ground, and you didn't need a Ph.D. to find it. Get price

Lead ore and mines

The early miners at Charterhouse and elsewhere probably found a rich bonanza of secondary lead ore deposits at or close to the surface, which pinched out at depth to thin primary veins. When the Cornish miners attempted to deepen the mines in the nineteenth century, the rich near-surface secondary deposits had been worked out and all that was left were the thin uneconomic primary veins.

Butte Montana Mining History

They found little gold, but got tantalizing assays of silver, frustrating because the remote area offered little hope of working those ores. By 1871 the placers had been worked to the limit of the water available and the area was nearly deserted except for a few dreamers who continued working on the veins. Get price

Silver mining

Silver is found in a native form very rarely as nuggets, but more usually combined with sulfur, arsenic, antimony, or chlorine and in various ores such as argentite (Ag 2 S), chlorargyrite (horn silver, AgCl), and galena (a lead ore often containing significant amounts of silver). ore often containing significant amounts of silver).
