Leaching equipment material
Thread Content
Medium at the start of leaching: hydrochloric acid (200 g/L) mixed with lead anode sludge (liquid-solid ratio 3:1)； After leaching, the concentration of hydrochloric acid in the liquid is 150 g/L, with Sb at 20 g/L, Bi at 120 g/L, and F ions at 10 g/L; the liquid-solid ratio is 5:1 ； Leaching temperature: 80°C, time: 4 hours ； Which sea friend can tell me what material is suitable for using in leaching tanks? Thank you!
No temperature requirement; titanium can be used, and if that’s not possible, an inner lining will also work
Do you mean being able to withstand 20% hydrochloric acid at 80 degrees?
Does the leaching tank have a stirrer? φ1.7*1.8m, with an effective volume of 3m3; its specifications are very similar to those of the phosphorus trichloride hydrolysis reactor customized for one of our clients. The material of the hydrolysis tank is impermeable graphite; it has been in use for over 8 years and is still in operation, with an expected service life of 10 to 15 years. The operating conditions of the hydrolysis reactor are: medium – water, phosphorus trichloride, hydrogen chloride, phosphorous acid ； Temperature: 80–105 degrees ； Pressure: Atmospheric pressure.
Fluorinated lining is completely unusable; PP will have to do as a makeshift solution
You can use our 1033, which is resistant to chlorine and fluoride
Steel-lined PTFE, steel-lined PP, steel-lined graphite, and the like can all be used.
