Determining the Rheological Properties of Mine Tailings

Determining the Rheological Properties of Mine Tailings

Tailings are leftover mineral byproducts of ore processing. The composition of tailings depends on the composition of the ore and the extraction process used to obtain the ore. Tailings typically consist of finely ground rock, processing chemicals, and small quantities of metals found in the host ore. Because of their small size and high water content, tailings are difficult to manage.

Mineral processing

Mineral processing

Dewatering is an important process in mineral processing. The purpose of dewatering is to remove water absorbed by the particles which increases the pulp density. This is done for a number of reasons, specifically, to enable ore handling and concentrates to be transported easily, allow further processing to occur and to dispose of the gangue.

The object of mineral processing, regardless of the methods used, is always the same to separate the minerals with the values in the concentrates, and the gangue in the tailings. The two most common measures of the separation are grade and recovery.
