3.2 Froth Flotation (Baseline Experiments) The froth flotation experiments were performed periodically based on optimum conditions investigated in previous work [1, 5, 34]. These conditions were 400 g/ton collector dosage, 250 g/ton dispersant dosage, 6 L/min air inlet, 20% solid content, and 1200 rpm as impeller speed.

Froth stability is a critical factor for flotation and even a small decrease in froth stability causes a decrease in the recovery of desirable minerals (Hadler and Cilliers, 2009, Hadler et al., 2012, Kowalczuk and Drzymala, 2017a, Kowalczuk and Drzymala, 2017). Although frothers improve flotation rate and recovery, a very high frother ...

The capacity of a section is from 800 to 1000 tons per 24 hours. Pulp is fed to the flotation machines with a consistency of 20 to 25 per cent, solids. From 0.5 to 0.75 lb. per ton of an oil mixture consisting of 90 per cent, coal-tar oil and 10 per cent, steam-distilled pine oil, is usually added. The pulp is neutral or very slightly alkaline.
The paper is about the froth flotation process and its application. It is a metallurgical process for the extraction of metals in a pure state from their ores: especially for sulfide ores. Froth ...
Froth flotation was developed at the Broken Hill mine, Australia, a century ago with the flo-tation of the common sulfide mineral, sphalerite. With this development, billions of tons of worthless rock containing a variety of valuable metals became ore. Anchoring this revolutionary development was the later introduction of xanthate as a ...

The flotation tests were performed, using 1.0 lb of A tall oil plus either 0.4 or 0.6 lb. of froth modifier per ton of feed, using the 11 different hydrocarbon "oil" type reagents (0.4:1.0 froth modifier/tall oil mixture used. Additional froth modifier was added separately to obtain 0.6:1.0 ratio.). Tap water was used for all tests.
The reverse froth flotation process with a pulp modified with 5 ppm MIBC plus 5 g/ton OA results in a separation of 86.12–13.88% in the concentrate and tails, respectively; taking into account that, as mentioned earlier, the tails section retains some of the NMF, this result is consistent with the XRD analysis of the tails as well as with the ...

The dominant flotation process currently used for processing of siliceous phosphates in Central Florida is the Crago "Double Float" process (Giesekke, 1985; Zhang et al., 1997).The simplified flotation flowsheet is given in Fig. 1.In this process, after desliming and sizing, the ore is conditioned with fatty acids and fuel oil at a pH of 9.0–9.5.
The mass flowrate of particles (ton/h), entering the froth by true flotation, was evaluated from direct measurement of bubble load (ton/m 3) and gas flowrate (m 3 /h). This information, together with the concentrate mass flowrate, allowed the estimation of the froth recovery of floatable mineral in a 130 m 3 rougher flotation cell.. It was found that …

The cost of treating 500 tons of ore per day by the old method was about 16s. per ton. The new installation occupies no more space than the old one and can take 1,500 tons per day at a cost of 6s. per ton. The two installations just described are typical of the way in which flotation is being applied in the metallurgy of gold ores.
