Processing complex slurries – Process productivity

The pipelines most likely to transport complex suspensions are downstream of value processing (e.g. tailings) with only a few in-process streams, such as reactor feeds, that may be problematic. One of the biggest challenges complex suspensions present is to the stable, trouble free operation of a pipeline.

Tailings Water Management McLanahan

There are several ways to store tailings following the production process, but the most common method is to pump the tailings slurry to a surface settling pond or impoundment. Settling ponds are large, manmade, relatively calm bodies of water used to store tailings. They allow the suspended solids in a slurry to separate from the liquid.
