The selectivity of the process is controlled by chemical reagents added to the pulp. The process is continuous and it is done on a large scale—10 3 to 10 5 tonnes of ore feed per day. Beneficiation is begun with crushing and wet-grinding the ore to typically 10–100μm.
The enriched concentrates usually contain 50 wt%–60 wt% REO, which can reduce the energy consumption and dosage of chemical reagents in metallurgical processes. The beneficiation methods of RE ores mainly include gravity separation, magnetic separation, electrostatic separation and froth flotation.
Flotation Reagents Dosing peristaltic pump plays an irreplaceable role in the precise flotation reagents dosing. Flotation agents modify mineral surface properties, increase or decrease mineral floatability, and make pulp properties and stability more favorable for mineral separation. ...
