Mill tailings are commonly disposed by deposition in a tailings pond which dries into a body of fine particles. Old tailings ponds can be a source of dust pollution because the fine particles are easily scoured from the surface by the wind. Weathering of the minerals in the fine tailings may be rapid.

Pyrite Gold Recovery in Copper Rougher Flotation Tailings

unintentional pyrite flotation is undesirable in a Cu Au ore flotation circuit due to the detrimental effect on Cu final grade. Therefore, in order to improve final concentrate grade, pyrite depression strategies (e.g. aeration, sulphite, cyanide addition, etc.) have been used over the years to minimise pyrite recovery.

Oct 27, 20160183;32;(1) Treating fine tailings or fluid fine tailings with a clay surface reagent such as a cationic collector prior to clay flotation may result in effective separation of a portion of the clay minerals (clay froth) from the non clay minerals (silts) such as quartz and feldspar (flotation tailings). The flotation tailings are easier to process because of the reduced fine clays and may be readily settled.
