Open pit mines are used to collect clay.
What is surface mining?
Almost all mining ventures involve some form of surface mining. Surface mining is the process of removing the top layer of the ground to obtain the minerals below. Surface mining is specifically used to recover materials like sand, gravel, stones, coal, iron, and other metals.
Types of surface mining:
1.Mining in Open Pits
- Similar to strip mining, open-pit mining involves extracting ore from an open pit that isn't then filled in. Ancient civilizations including the Greeks, Romans, and Persians engaged in open-pit mining for salt, granite, and marble for ages.
- When open-pit mines generate building materials like marble, granite, and limestone, they are generally referred to as quarries.
2.Extensive Mining
- A "highwall," or an unmined wall with overburden and exposed minerals and ores, is used in highwall mining to collect the ore.
- Highwalls are typically found at the edges of quarries and pit mines, allowing miners to access ore that would otherwise be too expensive to remove overburden from.
3.Dredging
- The more complex variation of panning for gold is dredging. In actuality, it's primarily connected to gold mining.
- Moving up a water table are floating dredges, which are barges equipped with conveyor belts and scoops, much like hopeful miners with their pans during the gold rush.
4.Removal of Mountains
- Mountaintop removal mining, which is hotly debated, is best suited for removing significant quantities of minerals from mountain summits, typically coal.
- The procedure entails using explosives to blast the overburden above the desired mineral seam.
