Rare earth minerals (REMs) contain rare elements (REEs) that are important in modern technologies due to their unique magnetic, phosphorescent, and catalytic properties. However, REMs not only non-renewable resources but also non-uniformly distributed on the Earth’s crust, so processing of REE-bearing secondary via recycling is one potential route ensure long-term sustainability REE supply.

Inorganic electrolytes are assumed to significantly impact the flotation performance of graphite resources; however, underlying mechanism is still unclear. In this work, effect three inorganic salts, including KCl, MgCl2, and AlCl3, was studied on graphite. Flotation results indicated increased recovery with addition KCl regardless pulp pH. MgCl2 improved under acidic slightly alkaline conditio...

• Cu 2+ -treated pyrite improved fine chalcopyrite flotation recovery as a carrier. CuSO 4 treatment of its hydrophobic interactions with particles. The mineral particles in is limited owing to the low collision probability between and air bubbles. carrier method can enhance particle by attaching fines coarse In this study, an attempt was made improve using Flotation experiments for finely grou...
