Tailings.info What Are Tailings?

The engineering characteristics of tailings are in most instances influenced by the degree of thickening and the method of deposition. It is therefore essential that while investigating the properties of tailings that the physical characteristics and material parameters (e.g. beach slope angles, particle size segregation, water recovery) that can occur as a result of varied …

Flat Ground Tailings Pond. This is a tailings pond built on flat ground and surrounded by dams on all four sides (Fig. 3).Its characteristics: there is no runoff concentration on mountain slope, water collecting area is small, flood discharge structure is quite simple, the tailings dam is very long, embankment requires large work quantities, and embankment …

Dusting Suppression at Tailings Storage Facilities

Abstract The authors review the methods of dust emission suppression at operated and abandoned tailings storages. The environmental impact of mineral dust particles and the after-effects are greatly varied. Dust suppression in surface layer of tailings ponds can use the most widely applied chemical methods, as well as mechanical and biological methods. The …
