Nickel is commonly present in two principal ore types—sulfide or laterite. Sulfide ores are typically derived from volcanic or hydrothermal processes and usually include copper (Cu) and/or cobalt (Co), and often precious metals such as gold (Au) or platinum (Pt), palladium (Pd) and rhodium (Rh) (the platinum group metals or PGMs) (Naldrett, 2002, Hoatson et al., 2006).
Apr 29, 2014· Not only can mining present a hazard to the environment, but it can also be seen as a toll on public health if appropriate measures are not taken to ensure that the mining process is being done as safely and efficiently as possible. Case studies from mines around the world have provided numerous success stories of corporations and private mines ...
In this article, Mr. John Wilson, Technical Services Asia, American PI Club (Hong Kong Office), explains why nickel ore is considered as ''the world''s most dangerous cargo''.
Nickel is not a cumulative poison, but larger doses or chronic inhalation exposure may be toxic, even carcinogenic, and constitute an occupational hazard. Nickel compounds are classified as human carcinogens based on increased respiratory cancer risks observed in epidemiological studies of sulfidic ore refinery workers.
Nickel is widely used in many areas in our daily life, for example coins, jewellery, mobile phones, magnets, electronics, glasses and kitchen wares. However, for human beings, it may also present significant health hazards. The hazard level depends on the amount of inhalation and the duration of inhalation. For example, it is one of the most common allergenic metals.
Examples of Preventive Measures avoiding hazards, and reducing risks. There have been significant improvements in the refining processes in the developed world by way of steps to reduce exposure. More widely steps should be taken to reduce exposure to nickel cations by direct contact either through reduction in nickel content of alloys or ...
Although Minnesota has a long history of iron ore mining, sulfide mining for copper, nickel, and precious metals has never been attempted. Prices for some metals, including copper, reached historic highs in 2011, and some companies have sought to mine Minnesota''s lowgrade sulfide ores.

In some states where old mining areas are common, such as Colorado and Nevada, current mine owners, government agencies, or other interested parties may undertake reclamation and safety mitigation projects that address hazards at these sites.
Cobalt is not found as a free metal and is generally found in the form of ores. Cobalt is usually not mined alone, and tends to be produced as a byproduct of nickel and copper mining activities. The main ores of cobalt are cobaltite, erythrite, glaucodot, and skutterudite.
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. These processes also have an impact on the atmosphere from the emissions of carbon which have ...
Jan 21, 2015· Pure nickel is a hard, silverywhite metal, which has properties that make it very desirable for combining with other metals to form mixtures called alloys. Some of the metals that nickel can be alloyed with are iron, copper, chromium, and zinc. These alloys are used in making metal coins and jewelry and in industry for making items such as valves and heat exchangers.
Mar 07, 2013· However, despite the beautiful appearance, nickel exposure, especially in industrial and occupational settings, can present significant health hazards. Effects of Nickel Exposure. Nickel is one of many carcinogenic metals known to be an environmental and occupational pollutant.
