Middlings, particles that belong in either the concentrate or the tailings, are also produced, further complicating the situation.

Tailings 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. Gravity separation is used in gold processing to recover the coarser particles, the finer

Tailings

Overview

Historically, tailings were disposed of in the most convenient manner, such as in downstream running water or down drains. Because of concerns about these sediments in the water and other issues, tailings ponds came into use. The sustainability challenge in the management of tailings and waste rock is to dispose of material, such that it is inert or, if not, stable and contained, to minimise water and energy inputs and the surface footprint of wastes and to move toward finding alternate uses.

Modern gold deportment studies SGS

grains are preconcentrated by gravity separation. This has similarities to the method described by Lastra et al. (2005), where the gold concentrated by hydroseparator is described. The concentrate only represents a certain proportion of the total gold in the sample, and therefore, a diagnostic leach test is done on the gravity tailings in order to
