| 发明名称 | Overburden/tailings mixtures for engineered tailings deposit control | ||
| 摘要 | A process for enhancing the solidification of tailings is provided comprising providing overburden having a moisture content ranging from about 15 wt % to about 25 wt % and comminuting the overburden to a first size; providing tailings having a solids content ranging from about 1 wt % to about 70 wt %; adding the tailings to the first sized overburden to form treated overburden and comminuting the treated overburden to a second size; and depositing the second sized treated overburden to produce a substantially solidified deposit. | ||

| 主权项 | 1. A process for enhancing the solidification of tailings comprising: a) providing overburden having a moisture content ranging from about 15 wt % to about 25 wt % and comminuting the overburden to form comminuted overburden; b) providing tailings having a solids content ranging from about 1 wt % to about 70 wt %; c) combining the tailings with the comminuted overburden at a tailings:overburden ratio ranging from about 0.2:1.0 (bulk volume) to about 0.4:1.0 (bulk volume) to form treated overburden; and d) depositing the treated overburden to produce a substantially solidified deposit. | ||
