Anti-flotation
Selective agglomeration ------- reverse flotation
Selective flocculation--------de-sludge--------reverse flotation
Reverse flotation -------- re-election
Also wish to roast --------- magnetic separation
High-sharp magnetic
Chlorination roasting --------- acid leaching
Bioleaching method
Reduction roasting --- magnetic separation and high-sharp magnetic separation method, effective for apatite
Reverse flotation, leaching process, adaptation to apatite, phosphate rock.
In the domestic research on phosphorus reduction in the "Ningxiang-style" high-phosphorus sturdy hematite ore,
For the phosphate rock, the dephosphorization is carried out by roasting, such as leaching, but the cost is high.
The use of flotation method is also more suitable to study effective flotation reagents and processes is the future research direction!
