Near the surface.
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.
Metals can be obtained efficiently and effectively through mining, recycling, and extraction processes. Mining involves extracting metals from the earth's crust, while recycling involves reusing metals from discarded products. Extraction processes, such as smelting and electrolysis, are used to separate metals from their ores. By utilizing these methods responsibly and innovatively, one can obtain metals efficiently and effectively.
Open-pit mining is a type of surface mining where large quantities of material are excavated from a large, open pit. It is commonly used to extract minerals such as copper, gold, and coal.
The three types of mining -strip mining,open pit mining,and shaft mining
Most metallic ores are produced through mining and extraction processes. Mining involves the physical extraction of ore from the earth, while extraction processes such as smelting, leaching, or electrolysis are used to extract the desired metal from the ore.
Daniel Jackling introduced the idea of open-pit mining
Surface mining is a type of mining method where minerals or ores are extracted from the earth's surface using machinery and equipment. This method is used when the mineral deposits are found close to the surface, making it more cost-effective and efficient compared to underground mining. Surface mining can include open-pit mining, strip mining, and quarrying.
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.
Obtaining metal ores from the ground is necessary for production of metals used in various applications. However, the extraction process can have negative environmental impacts, such as habitat destruction and pollution. It is important to balance the economic benefits of obtaining metal ores with the environmental concerns and work towards sustainable mining practices.

For coal or many other non-metallic ores, you will need crusher or grinding machines. For metallic ores you need a magnetic separation machine.
Open pit mining has been done since prehistoric times. At first, a quarry was probably opened to recover stone used in building. In this light, no one person or group can claim the introduction or "invention" of open pit mining. Certainly the scale on which we conduct open pit mining today doesn't begin to compare with these ancient methods. But the simple idea of opening a hole in the ground to recover useful material has been brought forward and continues.Daniel Jackling first introduced open-pit mining

Mining involves extracting ores from the ground, smelting involves heating the ores to high temperatures to separate the desired minerals or elements from the impurities, and refining involves further processing to purify the extracted materials into their final usable form.
