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.
