ABSTRACT The analysis of mineralogical, major, minor and trace elements in surface and ground water, metallurgical wastes and lateritic soil to evaluate the main environmental impact of nickel industry in the Moa district (Cuba) are presented here.
Unfortunately, environmental contamination from nickel mining is not uncommon, and has been documented in Canada (12), northwest Russia and Finland (13 15), and Cuba (16), amongst other places. The most common issues of environmental contamination are emissions of acid raincausing sulfur dioxide to the atmosphere, acid mine drainage ( 17 ) and heavy metals contamination in soil and

There are a number of key environmental themes which have emerged from this review and research on major trends in Ni mining and production: (i) economic resources over time; (ii) declining ore grades; (iii) increasing proportion of Ni laterites; (iv) the role of processing technology; and (v) environmental impacts associated with Ni production.
The delta is mostly dry due to the effects of lithium mining, cobalt and nickel, they could end up having a negative effect on the environment overall.
Mining remains an essential and growing part of the modern industry. By some estimates, it makes up nearly 45% of the total global economy, and mineral production continues to increase as demand for raw materials grows around the world. However, many mining techniques still in use can have serious impacts on both the mining site itself and the surrounding environment.
Nickel and nickelcontaining materials play an important role in the technologies and applications that are helping achieve key environmental policy objectives, such as reducing carbon emissions. Even though nickel is an essential element for plants, as with all metals and chemicals, excessive amounts can adversely impact the quality of the environment for flora and fauna.

According to IDTechEx, automakers are worried because nickel mining involves large quantities of waste and very little metal recovered. As demand for nickel grows, so do environmental concerns
The environmental effects of mining waste disposal at Lihir Gold Mine, Papua New Guinea raised environmental issues. Mining disasters and spills in reported an environmental row that was erupting in PNG around plans for a US38 million nickel mine whose tailings would be

For the optimization of the reaction process, the effects of additives, predehydration, and regulating mineral composition on the recovery of nickel and iron were investigated, and the results showed that the recoveries of nickel and iron after optimization increased to % and %, respectively.

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.
But what nickel gives with one hand, it takes away with the other: nickel production comes at an environmental cost that threatens to undercut its own clean energy credentials. Companies reliant on this metal must acknowledge their exposure to environmental
