Paste Thickening Considerations for Backfill vs. Tailings

Tailings are compacted to obtain geotechnical strength, limit air and water infiltration, and provide a working surface. Tailings for Mine Backfill To be considered for mine backfill, tailings must exhibit certain characteristics. There are specific tests that need to be completed to determine whether tailings can be used for the backfill at all.

I have only flirted with paste thickeners and agree that they are a technical risk when designing a mineral processing plant. On a uranium mine, test work was carried out on ore from drill samples ie from the resource itself. Based on this, a lot of equipment was designed using the rheological characteristics of the core samples.
