Dust-suppressing foam blankets

Ongoing research aims to assess the short and long-term potential of bioremediation processes to treat process-affected waters and meet acceptable water-quality criteria for preventing detrimental biological influences [635,638,640]. 

To avoid the occurrence of tailings ponds, and their associated problems, some mineral-process tailings are drawn off from the rougher and scavenger stages, thickened, de-watered in centrifuges, and then dried in, for example, gravity-fed, direct-fired driers for dry disposal.

Other applications of foam blankets are discussed in Sections 9.7 and 13.9.
