Gold occurs principally as a native metal, gold it is alloyed to a greater or lesser extent with silver, which is called gold can occur as sizeable nuggets, as fine grains or flakes in alluvial deposits, or as grains or microscopic particles (known as color) embedded in rock forms of gold are the minerals calverite (AuTe), aurostibnite .
A mineral detector is an electronic device used to find precious metals, gems, and stones buried under the Earth's surface. Mineral detectors can be metal detectors or ground penetrating magnetic loors. Mineral detectors are used to find minerals, such as gold and silver. They can also be used to find other precious metals, such as copper ...
· Place Borax and scrap gold in the furnace. The first thing you need to do is place your pieces in a graphite carbon crucible and add borax on top of it. This will help prevent impurities from existing when heating up the coal. Clear off all ashes inside the furnace. Turn on the melting furnace and slowly let it heat up.
· Install or open Google Earth. Once in google Earth, click Add –> Image Overlay. Type a name and browse to the loion of the 1909 georgia gold map on your hard drive. I use about 60% transparency, so I can see what I'm doing in the next step.

· Chemical and Molecular Biology Techniques: 1. Radiometry: The radiometric detection of microorganisms is based on the incorporation of a 14 Clabeled metabolite in a growth medium so that when the organisms utilize this metabolite, 14 CO 2 is released and measured by use of a radioactivity. 2.
· PB: You train them to sense certain smells that come from ore. We take ore samples from different mines and areas where we find the ore, and then we train them on that. Right now my dog can sense 20 – 30 different types of ore. They can discover an ore body that is as much as 12m under the ground.
DetectORE is a new technology, a new technology that allows quantitative gold analysis in the field with a portable XRF. Market Feedback. We're in the development phase and with this in mind have developed a series of market related questions to help us determine if we are on the right track. You can help us by taking the poll. At CSIRO, we solve the greatest challenges through .
The basic procedure was to place some goldbearing materials, such as river gravel, into a shallow pan, add some water, and then carefully swirl the mixture around so the water and light material spilled over the side. If all went well, the heavier gold nuggets or gold dust would settle to the bottom of the pan.
· 5. Hidee Gold Mine. The Central City area west of Denver was the center of the "Pikes Peak or Bust Gold Rush" and later dubbed "the richest square mile on Earth". While the town's casinos now dominate the landscape, over the hill is the Hidee Gold Mine. The Hidee offers great family fun with its 90minute tour.

These techniques of refining gold eventually reached the Spanish by 100 AD, who may have been just as mystified with the precious metal as Indians are today. Gold Ore Processing: Project Development and Operations, edited by Mike D. Adams speculated that up to 40,000 slaves were employed for gold mining in Spain at the time.
The nature of the ore deposit determines the mining and mineral processing techniques applied. Oxide ore deposits are frequently of such low grade (, 3 to 10 parts per million) that extensive mineral processing cannot economically be justified. In this case they are merely shattered by explosives and then piled into heaps for extraction by cyanidation (see below).
· The bestknown examples are the Currawong copper zinc deposit ( million tonnes of ore) in the Omeo Zone and the Mount Ararat copper deposit (1 million tonnes of ore) in the Stawell Zone.
