👉 Which is the best collector dosage for spodumene?
- In particular, the optimum pH and collector dosage were studied. It was found that the best ﬂotation performance occurs at pH 10 using 250 mg/L of sodium oleate. It was also observed that upon the addition of CaCl2, spodumene ﬂotation recovery increases to about 90%. In addition, poor ﬂoatability was found for spodumene when Na2CO3was
