Dec 17, 2016· Types of Water Pollution from Mining. There are four main types of mining impacts on water quality. 1. Acid Mine Drainage Acid Rock Drainage (ARD) is a natural process whereby sulphuric acid is produced when sulphides in rocks are exposed to air and water. Acid Mine Drainage (AMD) is essentially the same process, greatly magnified.
Mining companies have flooded into the James Bay lowlands, into the area now dubbed the Ring of Fire. They've found an enormous expanse of chromite, enough nickel for a mine and other metals that ...

Mar 31, 2016· With the rapid development of mining, problems related to groundwater in mining areas are becoming increasingly prominent. For example, due to drainage of groundwater, a series of environmental problems, such as pollution of groundwater and decline of aquifer levels, in mining areas have occurred (Dhakate et al. 2008).
3.1: Mine Drainage Water The State Pollution Control Board recorded the occurrence of Cr (VI) in the mine drainage water of the chromite mines in the Sukinda Valley in the late eighties. No techno economically viable treatment method for Cr(VI) was available then.

Jun 01, 1995· Chromite ore bodies in oxidized serpentinite therefore may generate hexavalent chromium from the inert chromites and cause hazardous chromium pollution of the water. With this end in view, a combined field and laboratory study has been made on chromite-bearing oxidized serpentinite rocks of Sukinda in Orissa, India.
Chromite mine soils were heterogenous mixture of clay, mud, minerals and rocks. The pH of the soils ranges between 5.87 and 7.36. ... (air and water pollution) in the major northern industrial ...

Chromite today is mined particularly to make stainless steel through the production of ferrochrome (FeCr), which is an iron-chromium alloy. Chromite grains are commonly found in large mafic igneous intrusions such as the Bushveld in South Africa and Travancore in India.
Sukinda is a classic example of pollution where the wastes are spread over a large area and residents are affected by the chromium through multiple pathways. The pollution problem from the chromite mines is well known and the mining industry has taken some steps to reduce the levels of contamination by installing treatment plants.
Mishra and Sahu (2013) reported that the environmental impacts of chromite mining in Sukinda Valley are caused by the presence of hexavalent Cr in mine drainage water, dust generation, overburden generation, and loss of biodiversity and forest. Open cast chromite mining generates a large quantity of overburden (Mishra and Sahu, 2013). If ...
Soil and Water Pollution. due to mining Anita Punia M.Phil 2nd Semester Introduction Miningis the extraction of valuable minerals or other geological materials from the earth from an orebody, lode, vein, seam or reef, which forms the mineralized package of economic interest to the miner.
Water pollution is caused by many factors including (but certainly not limited to): uncontrolled construction sites, leaking sewer lines, stormwater runoff, accidental spills and leaks, improper discharge of wastes, mining activities, foundries, animal waste, and others. Options for water pollution solutions are equally diverse.
Aug 18, 2010· The Sukinda Valley in Orissa state, India contains 97% of India's chromite ore deposits—used mainly to make chrome plating and stainless steel. Mining processes leave toxic chromium hexavalent in surface and drinking water, the soil, and the air. Residents suffer from gastrointestinal bleeding, tuberculosis, and asthma.
Chromium pollution due to leaching and weathering of chromite mine overburden in mine seepage water is a serious environmental problem. In an attempt to explore the indigenous chromate resistant and reducing bacteria from chromite mine quarry seepage, 145 aerobic, heterotrophic bacteria were isolated from 14 mine seepage samples derived from chromite mines of Sukinda valley and Baula-Nuasahi ...

Apr 01, 2019· Extensive mining of chromite in the area since several areas poses serious threats to the environment through pollution of toxic hexavalent chromium in soil and water bodies.
are affected by water pollution. Sources of Water in Orissa The main sources of water in the state are from the Bay of Bengal, from lakes like Chilika and Ansupa, from 11 rivers such as : Mahanadi, ... to mining of chromite ores cause nausea, skin ulceration, lung cancer and liver damage.
pollution of Dhamsala nala. Discharge of mine effluent in to Dhamsala nala without proper treatment increases hexavalent chromium at some stretches of the nala. The environmental impacts of chromite mining in Sukinda valley are; 2.1 Presence of hexavalent chromium in mine drainage water Open cast mining in the Sukinda valley is carried out at a ...
environmental chromium pollution on wildlife and we did not find any information directly relevant to potential impacts of chromite mining and ferrochrome production on terrestrial wildlife. Hexavalent chromium can negatively impact soil ecology in a variety of ways such as decreasing soil micro-organism presence, diversity and function.
Chromite today is mined particularly to make stainless steel through the production of ferrochrome (FeCr), which is an iron-chromium alloy. Chromite grains are commonly found in large mafic igneous intrusions such as the Bushveld in South Africa and India.
