Paste Thickening Considerations for Backfill vs. Tailings

Paste Thickening Considerations for Backfill vs. Tailings

The difference between a 10 in. slump and non thickened tailings can be 7% to 10% solids by weight. To pinpoint a percent solids in a process like this vs. a measurable slump can be difficult. This is an important factor mostly for backfill, but also for surface disposal.

For example, mineral sands slimes with a large portion of less than 2um particles are seen as a paste at 20% weight per weight (w/w) solids, but coarse copper tailings with a large portion of particles at 250um will not exhibit paste like behavior until approximately 70% w/w solids.

DEBOTTLENECKING OF THICKENERS IN A CHANGING ENVIRONMENT Abstract Thickeners are utilized in mineral processing for the purpose of solid liquid separation (dewatering). Thickeners separate an incoming feed slurry (i.e. water with solid particles of either product or tailings material) into two distinct streams; one

Deep Bed Paste Thickeners WesTech Engineering, Inc.

The WesTech Deep Bed Paste Thickener can thicken a tailings stream to non settling paste at solids concentrations approaching that of a filter cake. Design characteristics of the Deep Bed result in maximum water recovery, maximum underflow density, and paste with minimal slump.

The 34 m opposition thickener is now delivering a higher average underflow density of 5254% (often reaching up to 56%) than the 44 m tailings thickener. This increase is giving an additional 1116% residence time in the leach circuit, which helps to maximise recoveries.

Siddique (2006, 2007) states that methanogens in the tailings pond live and reproduce by anaerobic degradation, which will lower the molecular weight from naphtha to aliphatic, aromatic hydrocarbons, carbon dioxide and methane. Those archaea and bacteria can degrade the naphtha, which was considered as waste during the procedure of refining oil.

May 01, 20150183;32;These thickeners recover approximately 90 percent of the slurry water by volume. Most mining facilities would then deposit the tailings slurry direct into a tailings pond at about 40 percent to 50 percent solids. But this high rate primary thickener was inadequate to produce slurry densities required for the desired water reclamation.
