Gold pans have been around as a way to separate gold from lighter sand and gravel for a very long time. 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 …

In many countries, elemental mercury is used in artisanal and small-scale gold mining. Mercury is mixed with gold-containing materials, forming a mercury-gold amalgam which is then heated, vaporizing the mercury to obtain the gold. This process can be very dangerous and lead to significant mercury exposure and health risks.

Gold can occur in primary hydrothermal veins, volcanic or alluvial deposits. Although gold often occurs with quartz, it is more frequently associated with pyrites and …

The first shipment of gold from Siguiri took place in April 1998. The Siguiri mine produced 213,000oz in 2019 and 242,000oz in 2018. The decline in production was primarily due to lower plant feed grade and recovery. Around 3,056 employees and contractors work at the Siguiri mine. Total capital expenditure on the project for 2019 was …

A alluvial gold sluice box is an artificial channel into which gold-bearing gravel are flushed. With enough water to wash away all the large boulders that have been screened, the gold settles to the bottom of the water, where it is captured by slats called "riffles". The riffles act as tiny restrictions to the water's flow, creating low ...
