For example a tailings stream in an iron ore application could be thickened to 45–50 solids Newtonian slurry in conventional or highrate thickeners Conversely the same tailings stream could be thickened to 65–70 solids nonNewtonian suspension using a paste thickener This separation and concentration of copper and moly is called

Jan 18 2019 · Tailings is a biproduct of the processing of ore When the ore is processed the valuable minerals are separated leaving the finegrained waste material known as tailings The tailings are usually pumped from the thickeners through a slurry transportation pipeline and deposited at a dedicated tailings managementstorage facility

A byproduct of ore separation is tailings which are a mixture of water and finely ground rock from which most of the minerals of value have been removed Tailings may still contain metalbearing minerals and the mixture may also contain residues of reagents used in ore processing

Jul 08 2020 · “Over time the solid particles from the tailings mixture sink to the bottom of the pond and the excess water evaporates naturally” Historic tailings at Lamaque Canada What are DryStack Tailings Advancements in engineering and technology now allow for tailings to be dewatered prior to being placed in a tailings management facility TMF

Tailings Filling At present most mines use tailings to fill the minedout area Tailings need to be desilted 3070um to obtain high concentration about 70 tailings sand which also needs special treatment before filling The requirement of tailings sand is to obtain the highconcentration grit by removing the finegrained grade

The general rule is to add enough caustic soda to raise the slurry pH to about 9 Note that too much caustic soda is harmful for tailings ponds since it slows down the settling of fines Since the normal pH of the slurry is about 8 a very small amount of caustic soda is required to reach optimal slurry pH

Tailings may be dumped in or near water or transported by wind or water to contaminate the surrounding area Mine sites typically manage tailings by constructing ponds secured by dams According to the web site another strategy is to produce thickened tailings which are pressed or have chemicals added to remove excess water Thickened tailings can be mixed with cement and used in
