ABSTRACT:
This invention provides an apparatus for recovering a metal such as silver from an electrolyte in which the metal is dissolved. Into an open-topped tank is placed a close-fitting sleeve- or basket-like reticulum, of a material such as stainless steel screening. The reticulum includes vertical cylindrical sleeves and an electrode is centrally suspended within each sleeve. A voltage differential is applied between the reticulum and sleeve on the one hand and the electrode(s) on the other hand. The electrolyte is gradually introduced into the tank near the bottom inside the screen-like reticulum, and exit means are provided near the top of the open-topped tank through which the electrolyte can be drained off.
