Paste Thickening: Considerations for Backfill vs. Tailings
A gold mining operation in Ontario has fines that are 70% passing 20 microns and that is too fine to make a good backfill. The plant thickens and dewaters the full plant stream and 20% of that stream is mixed with 80% from local sand and gravel operations for backfill. That tailings facility has to handle much more disposal than backfill.

6 Filtration Testwork and Design To quantify the value of dewatering the tailings thickener underflow, the Owner engaged multiple vendors to undertake filtration testwork with the following objectives:
How to Size a Thickener
Knowing how to size a thickener and determine the capacity required to handle a pre-determined tonnage of a certain pulp, by overflowing a clear solution and obtaining the desired pulp density of thickener discharge, depends upon the settling rate of that particular pulp.

Comprehensive Guide to Mining Thickeners | Mining Pedia
Mining thickeners are crucial components in mineral processing operations, playing a vital role in enhancing process efficiency and managing tailings effectively. This comprehensive guide explores the key aspects of mining thickeners, including their functions, types, design considerations, operation, and maintenance.
Treatment of Gold Tailings in High Rate Thickeners
In 1988, a CIP gold treatment facility was installed at the Cosmo Howley gold mine in the Northern Territory. The nominal design tonnage of the facility was 1.2 Mtpa, and it was decided to include a 15 m Supaflo tailings thickener, based on bench-scale testwork which indicated a throughput of 0.8 t/m²h to achieve an underflow density …
