Materials Flows Analysis on the Beneficiation and

The aim of this paper is to explore material flow analysis, study the resource consumption and environmental impact of the production preparation process of typical rare earth materials. The results showed that in the beneficiation processes, producing one ton of rare earth concentrates (Rare Earth Oxide, REO50%) will also produces 27 tons of iron ore and 21 tons of tailings.

What is Beneficiation? - Info Bloom

For rare resources, beneficiation is critical, because it takes advantage of every scrap of material available. This practice can also make a marginal mining facility more practical than it might otherwise be, and may in fact be used to extract ore from a facility previously believed to be exhausted.

The beneficiation potential of the three ligands decreases in the order SHA > BHA > SA, as reflected by both sample grade and total rare-earth oxide (REO) recovery. From an ore sample containing 7.7% rare-earth oxide by weight, flotation with SHA results in the greatest total recovery of REO (66.6%), with an increase in grade to 33.4% REO.
