The environmental impact of iron ore mining, in all its phases of, from excavation to beneficiation to transportation, may include detrimental effects on air quality, water quality, and biological species

The mining operations like drilling, blasting, extraction, transportation, crushing and other associated activities are carried out in underground and opencast mines Mining operations damage the environment and ecology to an unacceptable degree, unless carefully planned and controlled There is a need for balance between mining and environmental requirements

Apr 02, 2018 Disadvantages of open pit mining One of the main disadvantages of this type of mining operation is the environmental impact it causes Since cyanide, mercury and sulfuric acid are used to remove the wastewater, groundwater and air are contaminated as toxic dust This is absorbed by animals and plants

Aug 26, 2008 Abstract Mining is widely regarded as having adverse effects on environment of both magnitude and diversity Some of these effects include erosion, formation of sinkhole, biodiversity loss and contamination of groundwater by chemical from the mining process in general and open pit mining

Impacts of Mining Mining can impact local communities both positively and negatively While positive impacts such as employment and community development projects are important, they do not off set the potential negatives We have found mining can negatively affect people by:

The plan must also consider the effects of mine subsidence, vibration induced by mining, processing, transport, or subsidence, and impact on surface water and groundwater These environmental items often dictate the economics of a planned mining operation and determine its viability

Opencast mining operations in South Africa remain one of the industrys main contributors to short and long term environmental damage, as they have a direct and cumulative impact on the air, water, soil and visual quality of the environment surrounding opencast mines, says Johannesburg based environmental management company I CAT Environmental Solutions

What Are the Disadvantages of Opencast Mining? Opencast mining, also known as surface mining or strip mining, has disadvantages that include disturbance of the environment and local ecosystems, exposure of radioactive elements and contamination of freshwater sources

Open pit mining or opencast mining refers to a method of extracting rock or minerals from the earth by their removal from an open pit or borrow It is a form of surface mining The term is used to differentiate this form of mining from extractive methods that require tunneling into the earth, like longwall mining

Apr 25, 2017 Mining is the extraction of minerals and other geological materials of economic value from deposits on the earth Mining has the potential to have severely adverse effects on the environment including loss of biodiversity, erosion, contamination of surface water, ground water, and soil

mining operations to minimise these impacts Good planning and environmental management minimises the impact of mining on the environment and helps to preserve biodiversity Whether coal is to be extracted by Opencast or by Underground methods of mining the selected method is to acknowledge the need to reduce environmental impact and to provide

Environmental impacts of mining can occur at local, regional, and global scales through direct and indirect mining practices Impacts can result in erosion, sinkholes, loss of biodiversity, or the contamination of soil, groundwater, and surface water by the chemicals emitted from mining processes
