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 …

Typical results in a coal beneficiation plant using spirals to treat fine coal indicated very little deterioration in performance with the under-slimed and deslimed feed material (−500 mesh) even when the feed contained ~50% of −500 mesh material. However, the clean coal ash reduced when the −500 mesh material was removed.
A beneficiation method and basalt technology, applied in chemical instruments and methods, magnetic separation, solid separation, etc., can solve the problems of restricting the development and utilization of basalt, achieve sufficient raw material sources, reduce production costs, and simple process flow
