| In 1904, Palmerton would begin producing spiegeleisen, taking advantage of the residuum from the zinc oxide furnaces. |
| The barite ore is massive and occurs within residuum derived from carbonate units. |
| Residual fuel is a blend of the residuum from the refining processes and lighter distillate to give the desired viscosity. |
| But figuring out exactly how to regenerate ammonia borane from the residuum left after hydrogen has been extracted remains a stumbling block. |
| Though the residuum is in one sense a social category, the concept implies that the group stands outside society and resists easy categorization. |
| But solutions can also form deposits by dissolving and removing valueless material, leaving a residuum of less-soluble ore minerals. |
