Jan 21, 2020 Environmental pollution from nickel may be due to industry, the use of liquid and solid fuels, as well as municipal and industrial waste. Nickel contact can cause a variety of side effects on human health, such as allergy, cardiovascular and kidney diseases, lung fibrosis, lung and nasal cancer.
Exploitation of nickel-copper (Ni-Cu) at Selebi Phikwe, Botswana is considered to have environmental and human health implications. Of particular concern is the labour force, which experiences a higher level of exposure to environmental hazards due to mining, compared to other categories of residents within the Ni-Cu mining environment.
Nickel is an essential micronutrient to plants and microbial processes. However, excess nickel may cause adverse effects to plants and animals. Global regulatory approaches for environmental protection focus on identifying nickel concentrations that do not pose risk to ecological communities in water, sediment, and soil.

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

Effects of nickel on the environment. Nickel is released into the air by power plants and trash incinerators. It will than settle to the ground or fall down after reactions with raindrops. It usually takes a long time for nickel to be removed from air. Nickel can also end up in surface water when it is a part of wastewater streams.
The overall aim of the paper is to examine the operations of the Copper-Nickel Mine in Selebi-Phikwe and assess its socio-economic and environmental impacts.
Oct 21, 2021 Opponents of copper-nickel mining near the Boundary Waters are cheering a decision from the Biden administration that could lead to a 20-year mining moratorium in the region. But supporters of the ...
Environmental hazards are present during every step of the open-pit mining process. Hardrock mining exposes rock that has lain unexposed for geological eras. When crushed, these rocks expose radioactive elements, asbestos-like minerals, and metallic dust. During separation, residual rock slurries, which are mixtures of pulverized rock and ...
Feb 21, 2019 Mining activities, including prospecting, exploration, construction, operation, maintenance, expansion, abandonment, decommissioning and repurposing of a mine can impact social and environmental systems in a range of positive and negative, and direct and indirect ways. Mining can yield a range of benefits to societies, but it may also cause conflict, not least in relation to above
Sulfide mining (also known as metallic mining) refers to mining operations which remove metals, such as copper, nickel, platinum and others, from sulfur bearing ores. The 1 Hudson, T.L., F.D. Fox, and G. S. Plumlee. 1999. Metal Mining and the Environment. American Geological Institute.
Environmental impacts from mining operations are significant and quite often severe, especially in developing nations which lack adequate management of the sector. In Zambia, impacts from mining results from both historical and ongoing mining operations, and the majority of them is located in the Copperbelt district.
Mining copper, nickel and other precious metals on the Iron Range will boost Minnesotas economy by leveraging existing mining infrastructure, putting the Eastern Mesabi Iron Range to work and revitalizing support businesses in a wide variety of industries.
