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.
Mining has always been among the most hazardous of occupations, and with the increasing demand for coal and minerals safety in mines assumes even greater importance. This article describes the present situation with regard to conditions in mines, the diseases and disabilities resulting from them, and measures that can be taken to prevent or ...

The predominant hazards identified were exposure to silica, coal dust, asbestos and diesel particulate matter.
Toxic metals, including "heavy metals," are individual metals and metal compounds that negatively affect people''s health. Some toxic, semimetallic elements, including arsenic and selenium, are discussed in this page. In very small amounts, many of these metals are necessary to support life. However, in larger amounts, they become toxic.

Apr 29, 2018· There are many environmental issues associated with nickel including greenhouse gas emissions, habitat destruction, and contamination of air, water, and soil. Nickel deposits are typically found in lowgrade ores (~12% nickel) thus making it highly .
However, mining in South Africa has the legacy of silica exposure, silicosis and tuberculosis, which contribute substantially to mortality and morbidity of miners. In this review, particulate and chemical hazards associated with mining industry in South Africa are identified and critical issues in the management of those hazards are discussed.
Underground mining, by its nature, presents a range of health and safety hazards that are different from those in other sectors. Some hazards, such as ground .
the specific hazards from the nickel in your workplace. What is nickel? Nickel is a silverygrey metal. It is used mainly: in alloys with other metals; as its compounds, which are often a bright green colour. Where is it found? Nickel can be found in: alloys, particularly nickel/copper and nickel.
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. Nickel is silverywhite. hard, malleable, and ductile metal. It is of the iron group and it takes on a high polish. It is a fairly good conductor of heat and electricity. In its familiar compounds nickel is bivalent, although it assumes other valences.
