Mine tailings have often to be stabilized by mixing them with cementing agents. In this study, the pore structure of gold tailings stabilized with Portland cement was evaluated by means of mercury intrusion porosimetry. The investigation was conducted on samples prepared with different fractions of tailings and cement as well as on samples …

The generated tailings in the mining sector are mostly disposed through conventional tailings management systems (e.g., storing in tailings dams). Due to the depletion of global ore deposits and new environmental rules, it is inevitable to consider new tailings management systems including recycling and reuse.

Generally, four restoration technologies, including physical, chemical, phytoremediation, and bioremediation, are used to restore the mining tailings. The working mechanism, advantages, and disadvantages of these techniques are described in detail.
