Correct answer: A. Pachuka tank
- A. Pachuka tank
- B. Agitated vessels
- C. Centrifugal extractors
- D. Packed towers
Explanation
A Pachuca tank is mainly used for agitation and gas-assisted leaching of solids, not liquid-liquid extraction. Agitated vessels, centrifugal extractors, and packed towers are all used for liquid-liquid contacting.
