Overall, AMD beneficiation and valorisation appears promising since the reclaimed water and the recovered minerals/metals could offset treatment costs and environmental impacts. However, the main challenges include high-cost, complexity, co-contamination in the recovered minerals, and the generation of a higly heterogeneous …

The beneficiation process generally follows a combination of pre-treatment and extraction techniques to recover lithium from the beneficiated concentrate in the marketable form. Pre-treatment induces higher reactivity to the monoclinic crystal-shaped α-spodumene by facilitating its transformation into tetragonal structured β-spodumene at ...

Basalt materials can be formed out of in-situ lunar regolith, with minor material beneficiation, by a simple process of heating and controlled cooling. The team then conceptualized a construction system that combines lunar regolith sintering and casting to make pressurized structures out of lunar resources.
