The earliest global traces of the impacts of mining on the environment, reconstructed from environmental archives, such as ice cores, peat bogs, lake and marine sediments, can be dated back to around 6500 bc. The first recorded global impact of mining was assigned to the Roman period due to Pbsmelting (Marx, Rashid, amp; Stromsoe, 2016).
Mines are known to cause severe environmental problems. Mining is the extraction of minerals and other geological materials of economic value from deposits on the Earth. Mining adversely affects the environment by inducing loss of biodiversity, soil erosion, and contamination of surface water, groundwater, and soil.

Environmental Impacts of Mining and Smelting The mining sector is responsible for some of the largest releases of heavy metals into the environment of any industry. It also releases other air pollutants including sulfur dioxide and nitrogen oxides in addition to leaving behind tons of
environmental science. In Africa, because of economic pressures and slower evolution of environmental awareness, local communities have been particularly exposed to the detrimental effects of contamination arising from mining and its effects on public health, agriculture and the environment. In addition, the legacy of mining has left
Description. Environmental studies and the occupational safety of mining activities are concerned with the study, assessment, and follow up of mining projects through the evaluation of their environmental impacts that result from mining processes and handling in order to protect and preserve the environment.
Environmental Impacts of Mining and Smelting
The impact of mining and smelting of metal ores on environmental quality is described. Mines produce large amounts of waste because the ore is only a small fraction of the total volume of the mined material. In the metal industry, production of Cu, Pb, and Zn causes the greatest degradation of the environment.
#0183;#32;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
Environmental Impacts of Lead Ore Mining and Smelting. Present day lead pollution is an environmental hazard of global proportions. A correct determination of natural lead levels is very important in order to evaluate anthropogenic lead contributions.
In this paper, the impact of mining and smelting of lead metal ores on environmental quality is described. Globally mines produce large amounts of waste because the ore is only a small fraction of the total volume of the mined material. In the metal industry, production of lead, causes the greatest degradation of the environment.
The mineral production is always associated with the solid waste generated in the form of overburden dumps, tailings and slimes. Areas around smelting and mining complexes are usually soiled by metals. Solid waste generated by mining production result in soil erosion, loss of
(i) To support efforts to address the environmental economic, social impacts and benefits of mining, minerals and metals through their life cycle, including workers health and safety. (ii) To enhance the participation of stakeholders, including local communities and women, to play an active role in minerals, metals and mining development throughout the life cycles of mining operations.
