The principal ground geophysical methods for alluvial gold exploration programmes are seismic, gravity, electrical and radiometric. Aerial magnetometry and spectrometry are the main airborne systems. Geophysical programmes are usually combined with photo-geology, remote sensing and geochemistry in regional studies.
This meant that the price of gold was fixed at $35 per troy ounce. Since that time however, the price of gold has increased by about 8% per year, more than twice the rate of inflation, and much more than bank interest rates.

They have been the standard equipment for mobile prospectors since the 1840s-1850s gold rushes, as they are small, portable and versatile. There is an interesting article (PDF) on the history and variety of gold pans in the World …
Alluvial gold in some Southland valleys has recently been found to contain a high mercury content. Mercury sulphide (cinnabar, HgS) from hydrothermal veins (see map) is commonly found with alluvial gold in gravels. Dissolved mercury in streams is elevated above background but is lower than drinking water limits.
The alluvial gold is mobilised from both the shear zones and the paleoplacers; grades increased with depth and are concentrated in layers of gravels and sandy sediments (Rae et al. 2009). The climate of the Kibi alluvial gold mining district is the wet semi-equatorial type with a bi-modal rainfall pattern that spans April–July and September ...

Since gold is extremely dense, it is easily trapped alongside other dense alluvial particles in these low-flow areas. The bits of gold found in these deposits of alluvium are called "alluvial gold.". Since alluvial gold is usually found in extremely small amounts, we have a blanket policy to not accept it at the refinery.
Samples were washed over a sluice box to generate alluvial gold concentrates that were oven-dried at 100 °C. Magnetic fractions were removed with a …

Gold was largely found in alluvial deposits where it was easily panned to find gold dust and grains or in veins in relatively shallow mines. Mine shafts were typically only a few metres deep and produced a mere 2.5 to 5 grammes of gold each so thousands of shafts were dug in a single gold-bearing area. ... West Africa was producing 10% of …
The gold can be hand picked, or carefully panned to purity, or better still the final concentrate sent to a lab for Total Fusion assay to give the grams of gold present. The oversize rock is then screened on a 15mm screen by hand and the -15mm is fed to a GoldJigga hand jig to recover any nuggets.
Placer mining ( / ˈplæsər /) [1] is the mining of stream bed ( alluvial) deposits for minerals. [2] This may be done by open-pit (also called open-cast mining) or by various surface excavating equipment or tunneling equipment. Placer mining is frequently used for precious metal deposits (particularly gold) and gemstones, both of which are ...
