U.S. Antimony INcreases Mill Capacity by 50 Percent
United States Antimony Corporation reported the start up of an antimony oxide mineral circuit at its Puerto Blanco antimony flotation mill located in Guanajuato, Mexico which increases its milling capacity from 150 tons per day to 225 tons per day. With the exception of USAC’s Los Juarez property, most antimony properties in Mexico contain oxide or mixed oxide-sulfide minerals. The sulfide minerals are recovered by flotation, but the oxide minerals must be recovered by gravimetric methods.
