Lead leaching method |
| abstract |
PROBLEM TO BE SOLVED: There is a demand for a method capable of treating lead, all of which is performed by a wet method. After lead sulfate in a lead-containing material is converted to lead carbonate with sodium carbonate, lead carbonate is added at a slurry concentration of 100 to 250 g / L, and the pH of the sulfamic acid solution is adjusted to 3.0 or less. Lead leaching method that can leach 80% or more. [Selection] Figure 1 |
