The flooding of abandoned iron-ore mines in the Lorraine Iron Basin (LIB) has led to a degradation of the local groundwater quality. As this water represents a potential resource of 300 million m 3, it is essential that we are able to predict its long-term quantitative and qualitative evolution in order to determine its future use.
We have also invested in recycling and conservation practices that make Oyu Tolgoi one of the most water efficient mines of its kind in the world. More than 80% of the water used in production is recycled, and on average Oyu Tolgoi uses less than 500 litres of water to process a tonne of ore – around half the industry average.
Ground water quality of Bailadila iron ore mine area amp its peripheral, Dantewada district, Chhattisgarh have been studied. 20 samples were collected from hand pumps in summer season and analysed in order to find out water quality index (WQI) and heavy metal pollution index (HPI).

It has been found that mining activities have deteriorated the water quality (both surface and ground water) in the region. Even the occurrence of water-borne diseases is positively and significantly related to water parameter index for water-borne disease in the mining region.
Some examples of mined substances include coal, gold or iron ore (Liang et al., 2021). Mining is an important part of human activity, providing society with various essential raw materials for manufacturing commodities, energy production, and other industrial and construction activities (McLemore, 2008). ... "Water quality in a mining …
Analysis of water quality for all the water bodies around the mines must be done to determine the source, effect and remedies of the pollutants and contaminants. This study deals with the analysis of water sample collected from iron ore mines. Similar work has been carried out by Ghosh and Sen (1999).

For over 40 years, taconite tailings, a by-product of taconite iron ore processing, has been used in northeastern Minnesota road construction projects as aggregate. The dominant uses have been as fill materials and in bituminous pavements. Over 125 million tons of tailings are produced annually by Minnesota's iron mining industry (Oreskovich et al., …
Samples of water were collected from iron ore mining areas of Tensa region of Sundargarh district. One sample was also collected from Kiriburu iron ore mines of SAIL. The analysis was carried out to determine the effect of iron ore mining on the water quality of the nearby areas of the mine.
The consumption of freshwater in mining accounts for only a small proportion of the total water use at global and even national scales. However, at …
The acidic conditions that lead to yellow boy also change the water quality making it difficult for the animals that inhabit the stream to survive and prosper. Iron County was built on the mining of iron and the Iron River watershed has absorbed the impact of these ore operations over the course of the 20th century.
The current analytical practical quantitation limit (PQL) for iron is 1 µg/L in fresh water and 2 µg/L in marine water (NSW EPA 2000). Iron is an essential trace element for both plants and animals, required by most organisms for essential growth and development, and iron deficiency could cause adverse biological effects.
Groundwater quality of Bailadila iron ore mine area has been studied. Groundwater samples were collected from hand pumps, and analysed in order to find out water quality index (WQI) and heavy ...

In India, there are over 34,000 people working in iron ore mining. The domestic iron and steel, sponge iron, ferrous alloys, and alloy steel sectors consume about 47% of the total output. Iron ore exports totaled 29.5 million metric tonnes during the years 1999 and 2000, with China and Japan each receiving 22% and 50% of such shipments ...
Pit lakes form when open-cut mining operations cease and the remaining pit fills with ground, surface and rain water. Mine pits, and therefore pit lakes, tend to have high depth-to-surface-area ratios with relatively flat bottoms and steep sides in order to minimise resource extraction costs (n.b., for the purposes of this review we are …
