Treating mine water as a resource is the only way to alleviate water shortage and the environmental pollution issues generated at mining sites in areas of northern and western China By investigating 77 coal mine water treatment stations in western China we sought to analyze the application status direct operating costs and the challenges of using membrane
In many cases most of the water used in mines is converted into wastewater The type and amount of toxic and heavy elements in mine effluents depend on the type of ore extracted and chemicals used during processing Kobya et al 2010 In addition other factors such as the type of method used for mineral processing mine lifespan weather conditions in
mine wastewater in a column reactor was investigated The investigated experimental parameters for synthetic solutions were initial pH temperature concentration resin amount solution flow rate and M Korkmaz et al / Desalination and Water Treatment 179 2020 63 74 65 jacketed column reactor was kept as constant at same work ing
water treatments are modeled after wastewater treatment plants which are machine intensive chemical dependant and require continuous operations and maintenance O & M staff Traditional solid mine waste remediation tactics involve covering of piles and water diversion tactics which do not treat wastes but rather mitigate their impacts
This paper presents a case study of an optimized combination of mine water control treatment utilization and reinjection to achieve the zero discharge of mine water Mine water has been considered a hazard and pollution source during underground mining so most mining enterprises directly discharge mine water to the surface after simple treatment
The currently used mining wastewater treatment technologies and methods were discussed Technologies such as SAVMIN® SPARRO® biogenic sulfide and DESALX® are among the approved and commercialised techniques for the treatment of mining wastewater and have been applied on a large scale Pilot stage treatment systems were also reported
Mine water is a by product of the process of coal mining which is a huge amount about × 1010 m3 in 2016 only in China For coal mine water including different ingredients the different water treatment methods have been used In China utilization of the treatment methods is summarized which presents the application situation technical characteristics economy
Acid mine drainage AMD is a major problem all over the world especially where coal and gold mine activities are common Once AMD is generated it is difficult to control the process and the treatment also requires high cost Aguiar et al 2016 Baruah and Khare 2010 Grande et al 2010 Qureshi et al 2016 AMD causes severe environmental impacts
Coal mine wastewater desalination More saline mine waster More than 80% of volume of mine water recovered Sewage primary effluent In textile wastewater treatment Calabrò et al studied the energy efficiency of a MD system with respect to distillate flux distillate purity and temperature polarization According to their results
This calls for efficient and innovative technologies to treat mine wastewater to enhance re use and recycling thus minimising portable water consumption By engaging a qualified and experienced water treatment specialist company mines ensure that they have adequate water reserves and mitigate the risk of water scarcity
Despite extensive research on acid mine wastewater treatment a systematic and comprehensive review that delineates its common attributes the progression of scientific methodologies and the focal points of research remains to be conducted This oversight leaves the benefits drawbacks and appropriate contexts for each treatment method
for wastewater treatment is the electrical coagulation pro cess which has attracted the attention of researchers in recent years due to its advantages such as simplicity envi ronmental friendliness and low cost The present review focused on the applications of electrocoagulation for mine wastewater treatment as well as metals recovery In addi
Traditional treatment by wastewater treatment plants WWTPs is successful in decreasing the nitrogen and carbon concentration of wastewater in most circumstances Furthermore they have been found to be ineffective in eliminating misuse drugs pharmaceuticals and the effluent water discharges from WWTPs have been characterized as micropollutants
