Slurry density is a core process variable across the entire concentrator — directly tied to reagent dosing, recovery, and product quality. This overview maps Pisonics products to three typical mining scenarios.
Concentrating overflow / underflow
Ball mill discharge, hydrocyclone classification, flotation feed — density at these points drives separation efficiency. Typical picks: abrasive but insertion-OK → PS7400 tuning fork; no tapping allowed (rubber-lined pipe) → PS7010 clamp-on; lab-grade accuracy → PS7000 acoustic impedance.
Hydrometallurgy leach circuits
Atmospheric, high-pressure (HPAL), and bioleach circuits routinely exceed 80°C and are highly corrosive. Need high-temperature corrosion-resistant variants — typically titanium or Hastelloy wetted parts. PS7400 high-temperature custom is the workhorse.
Tailings / paste-fill transport
Long-distance tailings lines and underground paste-fill use large bore (DN300+) and wide range (1.2–2.0 g/cm³). PS7300 differential pressure is cost-effective for large bore. PS7010 clamp-on is convenient for retrofitting existing lines.
Selection decision tree
All three scenarios are mining, but the engineering considerations differ completely. See our 'six-step selection process' or contact a Pisonics engineer directly.
