The effect of froth depth on air recovery and flotation performance
1. Introduction. In recent years, the importance of froth stability in determining separation performance in froth flotation systems has become increasingly recognised (Farrokhpay, 2011).Of the recent techniques used to determine froth stability, including water recovery (Wiese et al., 2011) and the froth stability column (Barbian et al., 2006), …

Since the recovery of feldspar is very low (less than 10%) using NaOL alone, this implies no research value. The recovery of feldspar is measured in the presence of activator Fe 3+. As shown in Fig. 8, the flotation of feldspar is enhanced by adding Fe 3+, and similar flotation recovery trends are observed in the four particle size ranges. …

Flotation Method in Archaeology
In flotation, the technician places dried soil on a screen of mesh wire cloth, and water is gently bubbled up through the soil. Less dense materials such as seeds, charcoal, and other light material (called the light fraction) float up, and tiny pieces of stone called microliths or micro-debitage, bone fragments, and other relatively heavy materials …
