Dry Stack Tailings Design Considerations

The shear strength of dry stack tailings will vary depending on the moisture content and density of the tailings and drainage conditions within the stack. From a design standpoint it is important to recognize that the density moisture content and drainage conditions within the stack are changing as more tailings are placed in the dry

Tailing Disposal an overview ScienceDirect Topics

After settling and selfweight consolidation the dry density of the undesic ed tailings is a function of the G s of the tailings solids. For coal tailings the dry density is about 1.8 t/m 3 due to their low G s while for metalliferous tailings the dry density is up to 1.5 t/m 3 due to their higher G s.

Dry stack facilities are also easier to close and rehabilitate require a smaller footprint compared to other surface tailings storage options i.e. higher density can be utilised in aggressive environments e.g. undulating and steep terrain and generate better regulator and public perceptions of tailings storage Davies and Rice 2001 .

Geotechnical Properties of Mine Tailings Journal of

The fine tailings were first oven dried then mixed with water at a predetermined water content of 10 and compacted into the sample mold in five layers with a dry density of 1.60 and 1.46 g / cm 3 for the iron and copper tailings respectively and finally saturated under a vacuum. The specimens for the permeability tests were 10 cm in

Measuring dry density of tailings as it desaturates Soil

I am looking for a novel way to measure the dry density of tailings as it desaturates due to an evaporation potential. I am trying to establish the relationship between moisture content and dry density. As a tailings settles out from the slurry it remains saturated and so working out the dry density and moisture content is simple.

pulp density and anticipated foundation soils. Figure 11.2 as proposed by Wates 1983 serves as a guide. Typically gold tailings have a settled density in a tailings dam of be tween 1250 and 1650 kg/m3 depending on the depth of tailings. A

Geotechnical Properties of Mine Tailings

The produced tailings were transported into a hydrocyclone separation facility and two kinds of tailings were generated i.e. coarse tailings from the bottom and fine tailings from the overflow of the hydrocyclone separation facility. The concentrations of the produced coarse iron and fine iron tailings from the Yuhezhai iron
