GENERAL KINEMATICS' dross reclamation system liberates precious metals from slag and dross, quickly recovering valuable material. Systems use either vibratory or rotary reclamation drums, depending on the product. The VibraDrum can be run in either a continuous or batch process through the company's automated retention system. The DuctaSprue uses more aggressive tumbling to abrade material and break apart and release slag, dross, and coke from recoverable metals.
