Extraction of Rhenium from Lead Sludge of Copper Production

Table 6

Results of rhenium desorption.

Desorption stage	Rhenium content in the eluate (g/L)	Extent of rhenium extraction into the eluate (%)
1	6.21	71.8
2	10.08	15.3
3	0.58	6.8
4	0.75	2.0

In the second and fourth stages, the eluate of the 1st and 3rd stages was used as desorbing solution, respectively.
