Tailings.info What are tailings? - Their nature and production

Tailings consist of ground rock and process effluents that are generated in a mine processing plant. Mechanical and chemical processes are used to extract the desired product from the run of the mine ore and produce a waste stream known as tailings. This process of product extraction is never efficient, nor is it possible to reclaim all ...

Data-driven modelling of the flocculation process on ...

The clarification of tailings slurry using polymer flocculants has been widely used in the mining industry to promote the cleaner production of mineral resources. In this paper, a data-driven prediction model was proposed using gradient boosting machine (GBM) for the non-linear relationship modelling and firefly algorithm (FA) for GBM hyper ...

Reprocessing Gold Tailings by Gravity Methods

Tailings originating from the gravity concentration of a gold ore containing about 14 g/t Au have been treated by various beneficiation methods. These tailings have been screened on the 147 and 74 micron sieves and the two coarsest fractions have been separated on shaking tables with unsatisfactory results, but the concentrates have been examined in polished sections for mineragraphic analysis.

Tailing Disposal Methods and Tailings Dam Construction Design

Tailings Dam Construction Design of slime is likely to slide and cause the dam to break away. The procedure usually adopted in such cases is to separate the tailing into coarse sand and fines in a classifier, and to use the coarse product to build up the wall ; the remainder of the pulp is discharged into the interior of the dam.

Mineral processing - Wikipedia

The cells in use at the moment can exceed 300 m 3. This is done as they are cheaper per unit volume than smaller cells, but they are not able to be controlled as easily as smaller cells. This process was invented in the 19th century in Australia. It was used to recover a sphalerite concentrate from tailings, produced using gravity concentration.

Tailings.info Hydraulic Mining of Tailings

It can be noted that the use of hydraulic mining for tailings can be to either reprocess the waste, mine the waste as a product, or for moving of the tailings to a more suitable location. Some tailings impoundments are hydraulically mined to not just process the tailings but to re-site them for environmental reasons.
