REMINE WATER

Solar powered water reuse and resource recovery in mining

A project that fosters the circular economy

Remine Water is a European project co-funded by the LIFE Programme that aims to improve and minimise mining wastewater discharges, and to contribute to the circular economy by reusing most of the discharged water and recovering valuable substances contained within mining industry process streams.

Mining is an important water consumer sector in Europe, as water is a critical component in the operation of a mine. In spite of the improvement in wastewater treatment processes and the implementation of partial reuse of inner water flows to reduce the water footprint, water is still discharged after ensuring its quality and dissolved metals are removed through precipitation as sludge for further management as waste.

The main goal of Remine Water is to transform the current process into a circular process. Remine Water will implement this objective by developing a system that allows water to be reused and the by-products contained in mining industry process streams, such as acids, metals and minerals, to be recovered so that they can be used again.

New water solutions for the mining industry

Remine Water will develop a pioneering treatment train for resource recovery and wastewater reuse in the mining sector. This innovative process will be powered by solar thermal energy, thus reducing its carbon footprint and achieving a more environmental and economic process. Moreover, Remine Water will develop a treatment train to recover minerals, acids and transition metals from mining industry process streams, which will be reintegrated in the processes.

Main outputs and achievements

The development of an innovative treatment train for mining industries will enable:

90%

of discharged water to be recovered for water reuse.

95%

decrease in the salinity for water reuse.
