Placer mining was the most widely used method of mining for gold because it involved extracting gold deposits from loose materials like sand or gravel in riverbeds. Miners could easily access these deposits without needing advanced equipment or deep excavation, making it a popular choice during the Gold Rush era.
Placer mining was largely replaced by hydraulic mining and hard rock mining methods. Hydraulic mining used high-pressure water jets to extract minerals, while hard rock mining involved digging tunnels and shafts to access mineral deposits underground. These methods were more efficient and able to extract minerals from deeper beneath the surface.
The first methods of placer mining involved using simple tools like pans and sluice boxes to separate gold nuggets from sediment in rivers and streams. Miners would manually dig and sift through the sediment to find gold deposits. Over time, more advanced techniques like hydraulic mining and dredging were developed.
In Colombia, the main types of mining are coal mining, gold mining, and emerald mining. Coal mining is a significant industry in regions such as Cesar and Boyaca, while gold mining is found in areas like Antioquia and Choco. Colombia is also one of the world's largest producers of emeralds, with most of the mining taking place in the Boyacá and Cundinamarca regions.
Gold mining in Mississippi is very limited and there are no active commercial gold mines in the state. There have been historic gold mining activities in the past, but they were not significant enough to sustain a long-term industry.

Placer mining was the most widely used method because it was affordable to a large number of prospectors. If you choose placer mining, the crusher and ball mill is common. You could get primary gold production from rock. If you want to get more pure gold production, you should choose other equipment, such as flotation cell, desorption electrolysis equipment and leaching agitation tank and carbon screen. There are equipment that used for mining in xinhaiindustry.com. You could learn more.

It was an easy method to find gold. All a man needed was a gold pan, and find a spot on the river to pan. Some got a bit more fancy with a sluice box or rocker to seek gold.

one way that i know of is placer mining, which is a method used by individual prospectors
There's placer mining, and hardrock mining.
Placer mining is looking for a specific mineral/claiming it/mining it Sluicing is a way of "mining gold"
