How Is Iron Extracted From the Earth? Iron ores in the form of hematite (ferrous oxide) and magnetite are removed from the earth through mining. The use of heavy mining equipment is necessary to dig out large pits in an area with a large deposit of iron ore; however, because iron does not occur naturally, it is necessary to use a blast furnace

What Are the Different Ways That Minerals Can Be Mined

Mining is the process of mineral extraction from an ore or rock seam. The minerals can range from precious metals and iron to gemstones and quartz. In ancient times, miners recognized a mineral rock formation from its outcrop at the surface. Modern mining technology uses geophysical techniques that involve measuring

How Is Platinum Extracted?  Reference

How Is Platinum Extracted? Reference

Platinum ore can be obtained through controlled explosions or by advanced mining techniques. Once it has been mined, the platinum is extracted from the ore in the same way. The platinum ore is not pure, so it is first crushed. This produces many tiny particles that can be treated.

Strip mining is used to extract ores that are near the surface in horizontal beds. is the deepest form of underground mining. It involves excavating a tunnel from the top to the bottom area of the mine. From this tunnel, the miners then dig long horizontal tunnels to get to the coal or other mineral ore.

that contain sufficient metal to be of practical and economic use are called ores. Metals are usually extracted from ores using a combination of heating and reduction with carbon in the form of charcoal or coke. Not all metals can be extracted from their ores in this manner and may need to be extracted by a process called electrolysis.

Mining

Mining

Mining is the extraction of valuable minerals or other geological materials from the earth, usually from an ore body, lode, vein, seam, reef or placer deposit. These deposits form a mineralized package that is of economic interest to the miner. Ores recovered by mining include metals, coal, oil shale, gemstones, limestone, chalk, dimension stone, rock salt, potash, gravel, and clay. Mining is required to
