Abstract
A process for electrowinning nickel or cobalt from an electrolyte in apparatus having spaced insoluble anodes and cathodes. Each anode is provided with diaphram means for defining an anolyte compartment. A frothing agent is introduced into the feed electrolyte which expedites the withdrawal of spent electrolyte and anodically generated gases.
