The wastewater at Sukinda chromite mines (SCM) area of Orissa (India) showed high levels of toxic hexavalent chromium (Cr VI). Wastewater from chromium-contaminated mines exhibit potential threats for biotic community in the vicinity. The aim of the present investigation is to develop a suitable phytoremediation technology for the effective removal of toxic hexavalent chromium from mines wastew...

we studied cu concentration on part of aras riparian vegetation. cu was selected as an index metal due to polluting the aras river through agarak copper mines drainage. results of cu concentration in indicator plant have been examined using spss16. considering the situation of the copper mines as well as the habitat of the indicator plant, two stations before and after the exit of the industria...

The main goal of the study was the analysis of the parameters of wastewater generated during the ex situ underground coal gasification (UCG) experiments on lignite from Belchatow, and hard coal from Ziemowit and Bobrek coal mines, simulated in the ex situ reactor. The UCG wastewater may pose a potential threat to the groundwater since it contains high concentrations of inorganic (i.e., ammonia ...

Cities worldwide are facing a growing water crisis with challenges from climate change, population growth, and deteriorating infrastructure that threatens economic development, social welfare, and environmental sustainability. New strategies are needed for water/wastewater treatment and distribution that will reduce the need to pump water over long distances and provide opportunities to reuse w...

The issue of wastewater treatment in open-pit mining mineral deposits is associated with great difficulties. Due to the constant tightening requirements for quality discharged wastewater, its sedimentation reservoirs and clarification ponds does not ensure achievement MPC values; addition, these facilities occupy significant areas land. It should also be noted that mines, as a rule, have severa...

The impact of discharges from abandoned metal and ironstone mines has been a much studied form of aquatic pollution in recent decades. Few attempts however, have been made to accurately determine the overall contaminant mass flux arising from abandoned mine sites at scales above catchment level. Such assessments are critical to determine the significance of former mining to national, regional a...

heavy metal removal from water and wastewater was investigated by using raw and modified diatomite from Iranian mines. Modification of diatomite was done by impregnating the diatomite surface with 0.35 g of manganese oxide in one gram of diatomite. This modified diatomite was named Mn-Diatomite. The surface area measurements for Mn-diatomite showed a 2.2 fold increase, hence higher removal capa...
