Mining Water Quality Application
Isaac Plains Coal Mine Isaac Plains is an open cut coal mine, in Northern Queensland, Australia. The Isaac Plains Project operates under an Environmental Authority (EA). One of the environmental monitoring requirements which must be met is monitoring water. These include potable water, mine affected water, natural creek flows, water releases, groundwater and the receiving environment. The site ...

Neutral mine drainage water-quality impacts from a form taconite mine
Abstract: Surface waters at the site of a former Minnesota taconite mine were reported to have solute concentrations elevated with respect to water-quality standards. Waste rock and ore generated from past mining were primarily from open pit mining of the Biwabik Iron Formation (BIF). The BIF is a variably bedded iron formation composed of inter-bedded cherty and slaty iron silicate and iron ...

Modelling the Long-term Release of Sulphate from Dump Sediments of an Abandoned Open Pit Lignite Mine
The generation of acid drainage from overburden spoil piles at open-pit lignite mines impacts water quality in large parts of the Lusatian mining area in Germany. The Lohsa Mine was exploited until the early 1990s and is to be flooded by 2005. It will then be used as a reservoir basin for the river Spree. Future acidity and sulphate concentrations in the surface water are of great interest ...

Influence of Copper Mine on Surface Water Quality
Aras water basin is located in northwest of Iran. Sungun mine which is the largest open-cast copper mine of Iran is located in this region and is in the primary stages of extraction. The influence of mining activity on the quality of regional surface water has been taken in to consideration in this study. Accordingly, sampling was done from 5 local streams in the study area. In order to consider ...

Analysis of mine water from four decommissioned pits in south-western Ghana – implications for remediation programmes for mine closure
Research into water quality status of accumulated water in decommissioned pits is a grey area in Ghana and could be of significant benefit in the effectiveness of remediation of pits after mining. Water sampled from four decommissioned pits in Amansie West District were analysed for their water quality status. Seasonal variations of physico-chemical parameters for determining water quality ...

Impact of using paper mill sludge for surface-mine reclamation on runoff water quality and plant growth
Paper mills generate large amounts of solid waste consisting of fibrous cellulose, clay, and lime. Paper mill sludge (PMS) can improve reclamation of surface-coal mines where low pH and organic-carbon levels in the spoil cover material can inhibit revegetation. When applied at high rates, however, PMS may adversely impact the quality of surface runoff. Therefore, we applied PMS at 0, 224, and 672 ...

Water Quality Data Logger for Monitoring Coal Mine Runoff
Water Quality Monitoring Solutions from dataTaker CAS DataLoggers provided an intelligent water quality data logging solution for an open-cut coal mine to monitor high salinity water runoff into local retaining ponds with a Water Quality Data Logger. The water from these retention ponds could only be released into the local river system when it was of sufficient quality to have no effect on the ...

Water supply and mining: the policy paradox in Ghana
Ghana has been highly successful in mining for over a century. However, one area of concern is the negative impact of mining activities on water resources: their quality and quantity. Mining companies are guided by rules and regulations, particularly those that have to do with the quality of water supply. Safe water supply is essential for improved health and quality of life for increased ...

The investigation of arsenic and heavy metal concentrations in soil, water and crops around abandoned metal mines
Soils, water and crops around abandoned metal mines can be contaminated by heavy metals from adjacent tailings and waste rocks accumulated during mining operations. The results indicate that the As, Zn, Cd, and Cr concentrations exceed the soil contamination standard in many soil samples of the nearby farmlands as well as the tailings sites. In the case of water quality, the As concentrations in ...

Recovering Lithium From Mining and Oil & Gas Wastewater
New membrane process could be a game-changer in lithium extraction efficiency Lithium-ion batteries power a wide variety of electronic devices, including mobile phones, laptops, and even electric vehicles, which could account for 60% of new auto sales by 2030. So, they will likely play an important role in the reduction of dependence on fossil fuels. Unfortunately, lithium mining can have ...

Mining Water Treatment: How to Meet Stricter Standards
Every industry needs certain supplies to operate. In the mining industry, one of those supplies is essential for human life, but it is in short supply: water. Coal mining companies utilize water to cool equipment and control dust, as well as extract, wash, and, in some cases, transport coal. Other mining companies use water to process minerals and reclaim precious metals from ore. The bad part is ...

Complex Contaminant Mixtures In Multi-Stressor Appalachian Riverscapes
Runoff from mountaintop mining altered watersheds in the Appalachian region (USA) is known to pollute headwater streams, yet regional scale assessments of water quality have focused on salinization and selenium. We conducted a comprehensive survey of inorganic contaminants found in 170 stream segments distributed across a spectrum of historic and contemporary human land use. Principal component ...

Assessing aluminium toxicity in streams affected by acid mine drainage
Acid mine drainage (AMD) has degraded water quality and ecology in streams on the Stockton Plateau, the site of New Zealand's largest open-cast coal mining operation. This has previously been attributed largely to the effects of acidity and elevated aluminium (Al) concentrations. However, the toxicity of dissolved Al is dependent on speciation, which is influenced by pH which affects Al ...

Why is mining wastewater treatment necessary?
During Industrial processes and mining, there are certain discharges of environmental pollution. This outcome is the growing concerns about the living atmosphere. As per the increasing concerns of contamination, there should be a lot of efforts and implementation to save the environment from its hazardous effects. Mining wastewater is originated from those mines where underground mining is ...

Water monitoring commences in mines of West Africa
As Sierra Leone looks to attract a new wave of mining investment in order to boost its economic profile, bringing water mine management standards in line with global best practices has become a priority. Government officials, academia, general citizens and companies have all become committed to improving standards with regards to water management in mining. As a key player in regulation ...

New study shows mining degrades waterways in 49 countries
A new study, led by Dartmouth researchers and published in Nature, reveals a distressing trend. Mining for gold and minerals close to rivers in the tropics is causing severe environmental damage in 49 countries. The research marks the first comprehensive investigation into how these mining activities are affecting river systems on a global scale, and the findings are alarming. The hidden cost ...

Introduction to Mining Wastewater Treatment: The Overall Guide
Mining waste comprises different types of rock, overburden, slurry and tailings from the processes of excavation and dressing. Further physical and chemical processing of a wide range of materials create additional waste from mining operations. Therefore, mine wastewater treatment is required, in order to avoid the contamination of the surrounding environment.This guide aims to explain ...
