In contrast to modern tailings from froth flotation, little is known about historic tailings from gravity separation. However, they may be of economic interest due to their higher metal grades compared to modern tailings. As an example for these types of historic tailings, the inner structure, as well as the economic potential (Pb, Zn, Cu, Ag, Sb), of the old Bergwerkswohlfahrt mine waste dump ...

Bitumen Extraction Explained | Oil Sands Magazine

This is achieved through a simple water-based gravity separation process, most of which occurs in a single large cone-bottomed vessel. The bitumen attaches to free air bubbles and rises to the top of the vessel, forming an intermediate froth product. The heavy sand sinks to the bottom and is pumped out to the tailings plant.

Jig concentrators - Wikipedia

Jig concentrators are devices used mainly in the mining industry for mineral processing, to separate particles within the ore body, based on their specific gravity (relative density).. The particles would usually be of a similar size, often crushed and screened prior to being fed over the jig bed.There are many variations in design; however the basic principles are constant: The particles are ...

TYPES OF TAILINGS FACILITIES – Bryan Ulrich

Jun 24, 2019· The sand fraction can be separated from the whole tailings using a simple gravity separation device called a cyclone. Because the sand settles at a different rate than the finer-grained silt and clay-sized particles, this gravity separation method, with no moving parts, can be used.
