Mining leads to waste heaps on the surface because during the mining process, large amounts of unwanted or low-grade material are excavated along with the desired ore. This waste material, known as overburden, must be stored on the surface since it is not economically feasible to transport it elsewhere. Additionally, waste heaps can result from the processing of the mined ore, where tailings containing unwanted materials are separated and stored above ground.

What are two main types of mining and how do they differ?
What are two main types of mining and how do they differ? Open cast mining, and underground mining. The reason they differ, is because underground mining is where they create shafts that lead to ore beds. Open cast mining, is the opposite of underground mining. I really hope this answer is useful! I love to help people get better at science. I hope I helped you guys! Bye.
How does surface mining affect the ground water?
Surface mining can contaminate groundwater through the release of chemicals and heavy metals used in the mining process. Removal of vegetation during mining can also lead to increased sedimentation and erosion, which can affect groundwater quality. Additionally, surface mining can alter the natural hydrological flow, potentially reducing groundwater recharge and increasing the risk of water pollution.
What are surface and subsurface mining techniques. what are some of the advantages and disadvantages of each technique?
Surface mining involves extracting minerals near the surface by removing vegetation and soil, while subsurface mining involves digging tunnels deep underground to extract minerals. Surface mining is faster, cheaper, and less hazardous to miners but can lead to environmental degradation and habitat destruction. Subsurface mining is safer for the environment but poses higher risks to miners due to the potential for collapses and gas explosions.
How has the environment been destroyed by mining?
Mining can lead to deforestation, soil erosion, and contamination of water sources with toxic substances from mining activities. It can also disrupt ecosystems and habitats, leading to loss of biodiversity. Additionally, mining operations can generate large amounts of waste, further contributing to environmental degradation.
Do mountains create waste?
Mountains do not create waste themselves. However, human activity in mountainous regions can lead to waste generation, such as littering, pollution from mining or tourism, and improper waste disposal, which can harm the environment and ecosystems in mountains.
Why is open cast mining lead to waste heaps on the surface?
For an open cut, the overburden has to be removed so that the ore can be accessed. An underground mine needs a tunnel to be dug through the host rock until you reach the ore. In both cases, there is usually waste rock which also has to be removed from the mine so your machines can get to the ore once you have reached the ore body.
What kind of surface or subsurface mining was done in Leadville Colorado?
In Leadville, Colorado, both surface and subsurface mining were conducted. Surface mining involved open pit mining for materials like gold and silver. Subsurface mining involved digging shafts and tunnels deep underground to extract minerals like lead and zinc.
When was silver first found?
Silver has been known since ancient times. Mentioned in the book of Genesis, slag heaps found in Asia Minor and on the islands of theAegean Sea indicate that silver was being separated from lead as early as the 4th millennium BC using surface mining.
What type of waste generated from pottery unit?
they use lead to glaze the surface of ceramics, and lead is hazardous to health. but technically speaking, it is a constituent, not a waste.....

What are the cons of surface mining?
The advantages of surface mining are: * It is cheaper to extract the ore or metal than underground mining * Less chance of workers dying from toxic fumes, therefore it is safer unlike underground mining. * It is also faster The disadvantages of surface mining are: * That it destroys the landscape and environment * Effects the habitats of fauna potentially effecting the existing ecosystem in that area * Flora is destroyed * Causes noise, air and water pollution

What is an example of mining waste?
An example of mining waste is tailings, which are the materials left over after the extraction of valuable minerals from ore. Tailings often consist of finely crushed rock, chemicals used in the extraction process, and water, and they can pose environmental hazards if not managed properly. Additionally, overburden, the soil and rock removed to access mineral deposits, is another form of mining waste that can lead to habitat destruction and soil erosion.
