AGQ Mining has been awarded a contract to carry out analytical geochemical characterisation and leaching tests on dump material from various radioactive mining areas in Portugal.

The Portugal-based public company, EDM (Empresa de Desenvolvimento Mineiro), awarded AGQ Mining & Bioenergy the contract.

The purpose of the project is to study the chemical stability over the medium and long term of residual materials present in these areas, which can assist the companies in predicting the future drainage that may occur. This will help estimate the potential environmental impacts and provide valuable information for the design and evaluation of the effectiveness of restoration measures and corrective actions, AGQ Mining said.

For this, in addition to the chemical and radiological analysis of the samples, simple and sequential column percolation tests will be carried out, as well as kinetic geochemical tests such as the humidity cells, it added.
