Tailings Fact Sheet

Tailings can be discharged using subaqueous below water or subaerial techniques. Subaerial deposition is more common than subaqueous as it forms a sloping beach toward the reclaimdecant pond. Subaerial can be done from a single discharge point, or multiple discharge points rotated around the facility. Subaqueous deposition is normally completed

Tailing Disposal An Overview Sciencedirect Topics

After settling and self-weight consolidation, the dry density of the undesiccated tailings is a function of the G s of the tailings solids. For coal tailings, the dry density is about 1.8 tm 3 due to their low G s, while for metalliferous tailings the dry density is up to 1.5 tm 3 due to their higher G s. Figures 2.4a and b show typical wet and dry density and w profiles with depth for ...

Upstream Raising Of Laterite Nickel Tailings Storage

The properties of tailings that emanate from laterite nickel processing plants are significantly different to most other mine tailings. They typically comprise a mixture of fine materials that are made up of altered clays, chemical residues and salts. Neutralisation processes that are undertaken prior to tailings discharge result in a high proportion of gypsum in the tailings.
