What are the effects of mining waste?
Excluding the hazard and the impact mine dump has on land, the hazard of toxic air pollution and the contamination of water in streams and river; quite a number of mine dumps are explosive and flammable. Furthermore, mine dumps interrupt the surface stability and result in adverse landscape transformation [14].
What does waste rock do to the environment?
This waste rock can in some cases have the potential to leak harmful elements into the environment. “A major environmental concern surrounds sulfide minerals, mostly pyrite, which react with oxygen and water, causing sulfide oxidation and resulting in the release of acid drainage.

What is the environmental impact of mining?
Mining: Environmental Impacts Mining can pollute air and drinking water, harm wildlife and habitat, and permanently scar natural landscapes. Modern mines as well as abandoned mines are responsible for significant environmental damage throughout the West.
How does mining affect the rock layers?
Frictional heat and sparks generated by mining equipment can ignite both methane gas and coal dust. For this reason, water is often used to cool rock-cutting sites. Miners utilize equipment strong enough to break through extremely hard layers of the Earth’s crust.
How does mining affect the rock cycle?
Explanation: Mining usually involves blasting rock to loosen it up so that overburden or ore itself can be removed. The rocks tend to get reduced in size so that weathering and erosion and act on them more quickly.
How is waste rock different from mine tailings?
Whereas waste-rock piles commonly have a large open and free-draining porosity, mine tailings drain slowly, maintaining a large residual moisture content under gravity drainage.
What are the problems resulting from the exploitation of mineral resources?
The exploitation of mineral resources has caused different types of environmental damage. Aigbedion and Iyayi (2007) , report ecological disturbance, destruction of natural flora and fauna, pollution of land, air, and water, instability of soil and rock masses, landscape degradation, and radiation hazards.
What are the problems with the mining techniques?
Most modern mining techniques have high water demands for extraction, processing, and waste disposal. Wastewater from these processes can pollute water sources nearby and deplete freshwater supplies in the region surrounding the mine.
Can stone waste chips be used in concrete production?
This Research Study describes the feasibility of using the Stone Waste chips in concrete production as partial replacement of natural aggregates in Indian context and to reduce disposal and pollution problems. As aggregates are being an important part of concrete by volume and cost.
How do you manage tailings and waste rock?
1. minimise the production of tailings and waste rock wherever possible 2. prevent waste rock and tailings from contaminating the surrounding environment 3. manage and control disposal of all tailings and waste rock 4. optimise the use of waste rock to ensure rehabilitation success.
