Early prospectors would extract shallow deposits of ore by?
panning for gold in rivers and streams, using a pan to separate the heavier gold particles from the sediment. This method was effective in finding surface-level deposits of gold and other precious minerals. It was a labor-intensive but relatively simple process that allowed prospectors to quickly identify potential gold-rich areas.
What category of mining would be used to extract ore close to surface?
Open-pit mining is typically used to extract ore close to the surface. This method involves a large excavation to access the ore deposits, which are found near the surface and easy to reach. It is a cost-effective mining technique for extracting shallow mineral deposits.
What is the method used to extract shallow deposits of coal from the earth?
The method used to extract shallow deposits of coal from the earth is surface mining, specifically using methods like strip mining and open-pit mining. These methods involve removing the overlying vegetation, soil, and rock to access the coal seams underneath, making it easier and more cost-effective to extract the coal.
What type of mining was required to find gold?
Gold mining typically involves both surface mining and underground mining. Initially, surface mining techniques such as panning, sluicing, and dredging are used to extract gold from shallow deposits. As the easier-to-access gold becomes depleted, underground mining methods like shaft mining and drift mining are employed to access deeper ore deposits.
What is subsurface mining?
Subsurface mining is a method used to extract minerals and ores that are located deep underground. It involves creating tunnels and shafts to access the deposits and extract the resources. This method is often used when the mineral deposits are too deep to be reached with surface mining techniques.

What type of mining is used to extract veins of ore deposits from the ground?
Vein mining is used to extract ore deposits from the ground. This method involves following a mineralized vein and extracting the ore from it by digging underground tunnels to access the vein. It is commonly used for minerals such as gold, silver, and copper.
Which type mining be used to extract a vein of ore form deep underground?
The type of mining used to extract a vein of ore from deep underground is known as underground mining. This method involves creating tunnels and shafts to access and extract mineral deposits located deep within the earth. The two main types of underground mining are called shaft mining and drift mining.
How are placer mining hydraulic mining and hard-rock mining different?
Placer mining involves extracting minerals such as gold from riverbeds and alluvial deposits using techniques like panning and sluicing. Hydraulic mining involves using high-pressure jets of water to dislodge rock and sediment to extract minerals. Hard-rock mining involves underground excavation to extract minerals like gold, silver, and copper from solid rock deposits.
What is a mining method in which overlying rock material is stripped away to reveal mineral deposits is?
Surface mining is a method in which overlying rock material is stripped away to reveal mineral deposits. This type of mining is used when the mineral deposits are close to the surface, making it easier and more cost-effective to extract them. Examples of surface mining include open-pit mining and strip mining.
What are the two methods used for mining coal?
The two methods used for mining coal are surface mining and underground mining. Surface mining involves removing layers of soil and rock to access coal deposits near the surface, while underground mining involves tunneling underground to extract coal from deeper deposits.
When will surface mining and subsurface mining be used?
Surface mining is used when mineral deposits are close to the surface, making it more cost-effective and efficient to extract them using methods like open-pit mining. Subsurface mining is employed when mineral deposits are buried deep underground, necessitating techniques such as shaft mining or drift mining to access them. The choice between surface and subsurface mining depends on factors such as the depth and location of the mineral deposits, environmental considerations, and cost-effectiveness.
What are metal bearing rocks sought after in mining called?
Metal-bearing rocks sought after in mining are typically called ore deposits. These deposits contain high enough concentrations of valuable metals such as copper, gold, silver, or iron to be economically viable for extraction. Mining companies prospect for ore deposits to extract and process the valuable metals.
