iron ore tailing thickener

Paste Thickening Iron Ore Tailings[1] | Particle Size Distribution ...

A tailings paste is a non-settling suspension of relatively high solids content with a non-Newtonian rheology. These characteristics offer the advantages of increased water recovery and surface disposal of tailings. A pilot scale paste thickener thickened iron ore tailings to underflow solids ranging from 55 to 80 wt%.
