Three methods of indigenous mining include panning for natural gold deposits in rivers and streams, using traditional pick and shovel techniques to extract minerals from small-scale surface mines, and using basic hand tools to dig tunnels into hillsides for underground mining operations.

What replaced the placer mining?
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.
Has mining of copper changed over time?
Yes, mining of copper has evolved over time with advancements in technology and mining techniques. Modern mining methods are more sophisticated and efficient, leading to increased productivity and reduced environmental impact compared to historical mining practices. Additionally, there is now a greater emphasis on sustainability and responsible mining practices in the copper mining industry.
Who invented open pit mining?
Open pit mining is a widely used mining technique developed centuries ago, and it is difficult to credit a specific individual with its invention. However, open pit mining has been practiced throughout history in various forms, with the ancient Romans known to have used similar methods for extracting minerals. The technique has evolved and is now a prevalent method in modern mining operations.
Where is coal dug?
Coal is primarily dug from underground mines. These mines are typically located in coal-rich regions and are accessed by tunnels and shafts. Surface mining methods, such as strip mining or mountaintop removal, may also be used in areas where the coal seam is close to the surface.
What were the first methods of placer mining used?
Placer mining (pronounced plasser, BTW) is mining for gold that is free of the rock. This is usually in the form of gold dust and fine nuggets. The simplest means, and the first used, was panning for gold in the rivers. You can also used a sluice box, where sand is shoveled into a trough with water running through it. Running water carries away lighter materials, and leaves the heavy gold in grooves on the bottom of the sluicebox.
What are the three gold mining methods?
Gold is recovered by three basic mining methods: placer mining of alluvial deposits, lode or vein mining, and recovery as a by-product of base-metal mining.
What are the surface and subsurface methods by which coal is commonly mined?
Surface mining methods for coal include strip mining, open-pit mining, and mountaintop removal. Subsurface mining methods involve underground mining techniques such as room and pillar mining, longwall mining, and shaft mining. Each method has its own advantages and challenges in extracting coal from the earth.
What are the different kinds of mining?
The three types of mining -strip mining,open pit mining,and shaft mining
What are some surface mining methods?
Some surface mining methods include open-pit mining, strip mining, mountaintop removal mining, and placer mining. These methods involve removing the overlying material to access the desired mineral deposits near the surface. Surface mining is often used for coal, metals, and other minerals that are located close to the Earth's surface.
How are the ore deposits removed by shaft and strip mining similar to the ore deposits removed in open pit mining?
In all three methods, ore deposits are extracted from the earth for processing. Shaft and strip mining involve creating openings to access the deposits underground, while open-pit mining involves removing ore from the surface. The main similarity is that in all three methods, the goal is to extract valuable minerals from the earth for further processing and use.
How did the methods of early miners and those mining company owners differ?

Mining methods for detrital and residual clay?
Strip mining is the most common method.
What are some early gold mining methods?
panning,shaft mining,cradling and puddling
What methods are used to find Gold?
Gold is typically found through mining methods such as placer mining, hard rock mining, and hydraulic mining. These methods involve extracting gold-bearing ore from the earth and then processing it to extract the gold. Modern methods also include using advanced technologies such as satellite imagery and geochemical analysis to locate potential gold deposits.
What methods do you use for mining?
