What are the environmental impacts of iron ore mining?
The mining of iron ore is highly energy intensive and causes air pollution in the form of nitrous oxide, carbon dioxide, carbon monoxide, and sulfur dioxide from diesel generators, trucks and other equipment. The mining of iron ore also causes water pollution of heavy metals and acid that drains from the mines.
What are the environmental impacts of mining in Australia?
Mining poses a variety of environmental risks, including potential impacts on ground and surface water quantity and quality, air quality, biodiversity, landscape stability and climate change. Australia’s mining sector has the skill, technology and motivation necessary to manage and mitigate these risks.
Which of the following are major environmental issues in mining activities?
Environmental issues can include erosion, formation of sinkholes, loss of biodiversity, and contamination of soil, groundwater and surface water by chemicals from mining processes.
How does ore affect the environment?
Mining and processing ore can have considerable impact on the environment. … The acidic water can leach heavy metals such as nickel, copper, lead, arsenic, aluminum, and manganese from mine tailings and slag. The acidic contaminated water can be highly toxic to the ecosystem.
How does coal mining affect the environment in Australia?
The extraction of coal and coal seam gas (CSG) will generate produced water that, if not adequately treated, will pollute surface and groundwater systems. In Australia, the discharge of produced water from coal mining and related activities is regulated by the state environment agency through a pollution licence.
What is Environmental Management Australia?
Environmental management plans describe how an action might impact on the natural environment in which it occurs and set out clear commitments from the person taking the action on how those impacts will be avoided, minimised and managed so that they are environmentally acceptable.
What are the environmental impacts of mining activity suggest the conservation practice for mineral resources?

The key environmental impacts of mining are on wildlife and fishery habitats, the water balance, local climates & the pattern of rainfall,sedimentation, the depletion of forests and the disruption of the ecology.
Why is mining bad for the environment Australia?
The environmental risks mining presents to land, water, biodiversity and people can be difficult to foresee but have the potential to last long after the mine has closed. The loss of valuable water and land assets affected by mining are highly significant to local communities and for long term sustainability.
Environmental and social impacts are divided into waste management issues, impacts to biodiversity and habitat, indirect impacts, and poverty alleviation and wealth distribution. … Disposing of such large quantities of waste poses tremendous challenges for the mining industry and may significantly impact the environment.
What are the positive and negative effect of mining in our environment?
Mine exploration, construction, operation, and maintenance may result in land-use change, and may have associated negative impacts on environments, including deforestation, erosion, contamination and alteration of soil profiles, contamination of local streams and wetlands, and an increase in noise level, dust and …
