Cobalt Recovery By Flotation

Continuous Flotation Testing To Recover Cobalt From

Mineralogical analyses showed the cobalt present as a distinct mineral phase, predominately siegenite, amenable to a physical separation method such as froth flota­ tion. Flotation was chosen for recovery because of easy adaptation by the mills. Unit processes of grinding, conditioning, and flotation were studied individually and in con­
