| The mill produced a lead concentrate, a zinc concentrate, and pyritic tailings. |
| This could affect threshing efficiency since tailings are returned directly to a combine's rotor or cylinder for rethreshing. |
| The uranium tailings damage the lining of the lung and increase the risk of developing cancer when breathed in. |
| Mine wastes have been generated over the last several centuries of mining, the two primary mining wastes being mine tailings and waste rock. |
| We've come to the Kennedy Mines Tailing Wheels, which were once these four huge wheels that carried the tailings, or residue, from the mines. |
| Thus, the present invention advantageously avoids the production of tailings sludges caused by clay dispersion. |
