This technique has endured for thousands of years, suggesting to geologists and historians that the region is the same ancient Colchis Kingdom as referenced in the Golden Fleece myth. The researchers wonder if the story of Jason and the Argonauts may have been based on a real and ancient mission to learn the secrets of the technique of gold extraction, or to retrieve sheepskins glittering with

How did early prospectors find and gather gold? Learn a little more about some early gold mining techniques and discover the interesting origin of the legend
Mining technology consists of the tools, methods, and knowledge used to locate, extract, and process mineral and metal deposits in the earth. The methods used to locate ore bodies range from ontheground reconnaissance by prospectors to remote sensing techniques such as satellite imagery.

Life on the Australian goldfields. includes a chapter on early gold mining techniques from across Australia, and includes a wide range of images showing mining
Early gold mining techniques Long ago, individuals did not have to search as extensively as they do today to discover gold deposits, and the mining processes used reflected the ease of extraction. When it was discovered that the commodity could be found in shallow riverbeds, early miners used placing, a practice using a shallow metal pan to separate lighter river soil from heavier gold flakes.
Mining technology on the central Victorian goldfields in the 1850s and 1860s Early techniques. The efforts of the first gold seekers were mainly focused on the shallow alluvial deposits found in central Victoria, particularly in the BendigoBallarat area.
Summary. Historically, the majority of gold was mined from quot;placer depositsquot;, where gold has settled out of an existing or ancient waterway downstream of where nuggets had eroded out of rock early miners also used an early form of hardrock mining, digging solid veins of gold out of rock, where mineralized water had deposited it over thousands of years.

Gold mining is the process of mining of gold or gold ores from the ground. There are several techniques and processes by which gold may be extracted from the earth. Placer mining Placer mining is the technique by which gold that has accumulated in a placer deposit is extracted.
Two of the best examples we have of wellestablished underground mining techniques come from the Laurion silver mines, south of Athens in Greece especially important in the 5th century BC and the Roman Rio Tinto silver mines in Spain, both using mining technology only slightly improved upon from their earlier Bronze Age predecessors who worked these same mines as early as 3000 BC.
Since the early 20th century, gold miners have increasingly turned to machines known as dredges, which are capable of making poor ground profitable. Using traditional techniques but on an industrial scale, dredges are capable of scooping thousands of cubic feet of gravel in a single day each day.
