5 Pans. Panning for gold was also known as "placer mining." Early miners sat by riverbeds, scooping wet soil into shallow metal pans. They swirled the pans, washing away the dirt to hopefully discover particles of gold. Though more complex equipment was eventually invented, pans were still a useful tool to distinguish gold from dirt.
Placer mining is the technique by which gold that has accumulated in a placer deposit is extracted. Placer deposits are composed of relatively loose material that makes tunneling difficult, and so most means of extracting it involve the use of …
Gold mining is the extraction of gold resources by mining.Historically, mining gold from alluvial deposits used manual separation processes, such as gold panning.However, with the expansion of gold mining to ores that are not on the surface, has led to more complex extraction processes such as pit mining and gold cyanidation.In the 20th and 21st centuries, most volume of …
the Requirements for a clean technology in small scale gold mining (1) - the technology must be technically efficient (more than the traditional methods) Technical-economical criteria: - the equipment, if possible, needs to be manufactured locally - long life span - simple and safe handling and maintenance (also by less qualified personnel)

When gold was found, the miners would then move on to equipment such as sluices and rockers so that they could handle a higher volume of sand and gravel. Eventually, these easy to find minerals would be worked out, and higher forms of technology would be utilized to get at the gold, including hydraulic mining and dredging.
