Production. Lead. An Akins type classifier in a lead concentrator near Creede, Colorado where old mines have been reopened. The classifier sends back to the ball mill all ore not crushed to pass a screen of specified mesh. Creede, for many years a "ghost town," has resumed the activities that made it an important lead-producing center years ago and is now producing much metal vitally needed for the war effort.
