Mine Wastewater Effect on the Aquatic Diversity and the Ecological Status of the Watercourses in Southern Poland https://www.mdpi.com/2073-4441/16/9/1292?fbclid=IwY2xjawLTLvNleHRuA2FlbQIxMABicmlkETE1TjY0T1RVWW9qOTh3YWlWAR5Ww2KuxFX4nwkSy-ZYFdvr3sNYVkuSrp7R4HMqDB1daTiunAZoUgwQ419uqg_aem_U-2YQJ-FbL6Ua6ukmv5HZg This research was partially supported by Polish Ministry of Science and Higher Education “PMW” programme 2019-2024, agreement 5050/LIFE/2019/2 Coal mining activity contributes to energy security and employment occupation, but is associated with environmental deterioration. Coal combustion leads to GHG emissions, while coal mining results in the generation of saline effluents. These effluents are discharged in inland surface waters, applying significant pressure on their quality, with a negative impact on aquatic life and the economy of a region. This study includes water samples

Innovative solution for the recovery of clean water and high-purity minerals from the coal mine sector https://www.sciencedirect.com/science/article/pii/S0011916425005971?via%3Dihub Coal mining activities generate massive volumes of highly saline wastewater that cause significant ecological damage once they end up in the environment. Saline discharges contribute to the salinization of soil, the disruption of the aquatic flora and fauna, and the degradation of surface water quality. To address this issue, a near-zero liquid discharge (near-ZLD) system has been designed and constructed to treat coal mine wastewater before its discharge into the environment. The pilot system included membrane, precipitation, and thermal technologies to desalinate the

The concept of circular water value and its role in the design and implementation of circular desalination projects. The case of coal mines in Poland https://www.sciencedirect.com/science/article/pii/S0011916424002121?via%3Dihub This paper focuses on the ”circular water value” concept in the context of coal mining by comparing the circular value of two different cases. The findings highlight opportunities for enabling a transition in coal mining regions through circular practices.
