- •
Low oleate dosage greatly improves the dispersibility of rock dust particles.
- •
High oleate dosage adversely deteriorates the dispersibility of rock dust particles.
- •
Monolayer adsorption of oleate on dust surface occurs within 0.1 to 0.15 wt% oleate.
- •
Hydrophobic interaction facilitates the agglomeration among super hydrophobic dust.
- •
Precipitated calcium oleate nanoparticles tend to nucleate and agglomerate under high oleate dosage.
