Health effects of mining very severe The mercury used in mining causes a number of different health problems, including neurological disorders and kidney diseases. Besides mercury-poisoning, people living around mines are polluted by lead, zinc and copper.

Lithium mining carries high environmental costs. Mining companies prospecting lithium in northern Tibet, salt plains of South America, and Chile as well as lithium at Bolivia's Salar De Uyuni require extensive extraction operations and water in a dry land.
Uranium mining and processing are associated with a wide range of potential adverse human health risks. Some of these risks arise out of aspects of uranium mining and processing specific to that enterprise, whereas other risks apply to the mining sector generally and still others are linked more broadly to large-scale industrial or construction activities.

Spodumene theoretically contains 8.03% Li2O and therefore the production of this mineral is greatly increasing because of the expanded use of lithium in the manufacture of high temperature insoluble lubricants, ceramics, pyrotechnics, non-ferrous welding fluxes, air purifying agents, and hydrogen isotopes. Extracting Lithium from its Ore The problems of spodumene mineral dressing depend on
Due to its high energy generation potential, coal is widely used in power generation in different countries. Although, the presence of carbon, hydrogen and sulfur in coal facilitates the energy generation in coal combustion, some pollutants including COx, SOx, NOx, particulate matter (PM) and heavy metals are accumulated in air and water and lead to severe environmental and health impacts as a ...
What is Spodumene? Spodumene is a pyroxene mineral that is typically found in lithium-rich pegmatites.It is usually associated with other lithium minerals such as lepidolite, eucryptite, and petalite.Spodumene has a chemical composition of LiAlSi 2 O 6 but small amounts of sodium sometimes substitute for lithium.. Throughout most of the 20th century, spodumene was the most important ore
β-spodumene. The α-spodumene is virtually refractory to hot acids. As a result of the phase transformation, the spodumene crystal structure expands by about 30% and becomes amenable to hot sulphuric acid attack. Due to this expansion, the specific gravity of the spodumene decreases from 3.1 g/cm3 (natural α-spodumene) to around 2.4 g/

The continued growth of coal mining has left communities with pervasive and irreparable damage. Until recently, however, the effects of coal on human health have been largely ignored and mining has continued without many appeals for improvement. In both the United States and China, industrial achievements have created a legacy of pollution that is taking a major toll on human health. Despite ...
Jan 21, 2015 The levels of zinc that produce adverse health effects are much higher than the Recommended Dietary Allowances (RDAs) for zinc of 11 mg/day for men and 8 mg/day for women. If large doses of zinc (10-15 times higher than the RDA) are taken by mouth even for a short time, stomach cramps, nausea, and vomiting may occur.
1938 "Stop Silicosis" Video. The hazard of respirable crystalline silica exposure has been known for decades. This 1938 video features former Secretary of Labor, Frances Perkins (1933-1945), and describes both the hazards associated with silica exposure and the U.S. Department of Labor's early efforts to ensure safe and healthful working conditions for America's working men and women.

Health Effects of Uranium . Uranium is a metal that exists naturally in the earth. There are small amounts of uranium in almost all the soil, rock, and water in the world. It can move through the environment in rain, wind, and other natural processes. People have used uranium for building military shielding, weapons, planes and helicopters.
