The aim of this article is to present priority themes covered by the Health and Safety training programs of the Greek and European mining industry during the last decade. Mining is considered as an industry presenting high occupational risks. The Int...

High purity magnesia refractories have been tested for their resistance to iron-rich converter slags of ferronickel production. Laboratory tests were performed using crucibles made from magnesia refractories filled with slag at temperatures up to 170...

Although there is a widely expressed need for the adoption of new didactic approaches that promote the active participation of learners, especially in tertiary-level education, research endeavors in this topic are limited. Seeking to contribute to th...

Most hydrometallurgical solutions usually contain high levels of ferric iron, which is often regarded as a major and problematic impurity. Precipitation of Fe(III) by raising the solution pH results in a voluminous amorphous residue that is particula...

In every mine in the world, the result of the process is a slurry material called tailings. Today, more than ever before, the mining industry is looking for technical solutions to dewater mine tailings to eliminate the risk of tailings dam failures....

Carbon dioxide sequestration by calcium- or magnesium-containing minerals has been recognized as a promising processing route for the permanent and safe storage of carbon dioxide. In this study, the wet carbonation of lignite fly ash containing appro...

Scandium extraction from the Greek bauxite residue has been demonstrated at an industrial pilot plant at MYTILINEOS. This work comes as the result of the H2020 SCALE collaborative research project. By combining sulfuric acid leaching and II-VI Select...

The extraction of antimony and arsenic from galena concentrates by leaching with strongly alkaline sodium sulphide solution are investigated. The effects of leaching parameters including sodium sulphide and sodium hydroxide concentrations in the leac...

The present study focused on investigating the high-temperature reduction of bauxite residue, also known as red mud. A series of reduction experiments on red mud was performed to investigate the influences of temperature (1400, 1450, and 1500 °C)...

The treatment of spent nickel metal hydride batteries (NiMHs) of Lexus vehicles to recover nickel (Ni) and cobalt (Co) as well as rare earth elements (REEs) including La, Ce, Nd and Y was investigated. Co-extraction of Al, Fe, Cr and Cu has also been...
