Abstract
Disclosed is a fiber bundle contactor in which fibers are packed in high density within a column. When two liquid phases flowing in parallel, one of which contains the desired components, are contacted with the entryway of the highly packed fiber bundle, the two liquid phases are very thinly dispersed among gaps around the respective fibers by capillary action induced by the clearance between the fibers. By means of this capillary action, the two liquid phases are maintained as a continuous stream, and the two phases are brought into very intimate contact, thereby ensuring a very large surface area for liquid-liquid extraction to proceed.
