Froth Flotation Hazen Research

We have studied not only the flotation of sulfides, gold ores, iron ores, coal, oil shale, and many other nonmetallics, but also soluble salts, oxides, and some uncommon materials from waste streams. Flotation techniques we have used in addition to the ordinary air froth type include unusual procedures such as ion, precipitate, and agglomeration flotation using inert gas, air, or in situ gas generation.

Froth flotation circuit design and basic testwork

Most flotation circuits include an initial stage of rougher flotation, followed by a scavenger stage of flotation. The objective of passing through the rougher and scavenger flotation circuits is to maximise recovery of the desired minerals into relatively low grade concentrates that may typically contain 5 15 weight percent of the ore feed, (directly related to ore grade).

Flotation Circuits. Flotation circuits are typically comprised of rougher, scavenger and cleaner flotation banks. Rougher and scavenger banks are focused on recovery and thus provide maximum residence time. Rougher banks can be large with the number of cells being 5 or greater. Scavenger cells are the last line of defense for avoiding losses.
