| 20110083532 | PROCESS FOR INCREASING DROSS RECOVERIES - A process for increasing the percentage of metal recovery from dross containing metal particles of different sizes having oxide and salt components adhered thereto. The process includes crushing and tumbling the dross to mechanically remove all of the oxide and salt components from the larger of the metal particles, separating the larger metal particles from the removed oxide and salt components and the smaller metal particles to provide a supply of larger metal particle concentrate, separating the removed oxide and salt components from the smaller metal particles, mechanically impacting the smaller metal particles to remove any additional oxide and salt components from the smaller metal particles, and separating the smaller metal particles from the additional oxide and salt components to provide a supply of smaller metal particle concentrate. | 04-14-2011 |
