Pyrite flotation separation and encapsulation in tailings dams is proposed as a viable way to chemically stabilize tailings. Characterization of potential acid mine generation in tailings led to an innovative process in which acid-generating pyrite is separated by flotation from the coarse tailings and incorporated into the slime zone. This creates pyrite-free neutral …

In the preparation of bauxite-tailing-based ceramics, appropriate Fe 2 O 3 can promote the formation of liquid phase, thus promoting the ceramic compact and phase transition of mullite, and corundum. A too-high Fe 2 O 3 concentration will lead to the reduction of liquid phase components, which is not conducive to the preparation of ceramics.
